Test. This type of variation from one sample to another is called sampling error. Pictogram is a popular method of presenting data to the “man in the street” and to those who cannot understand orthodox charts. Tabular presentation Visual Presentation Graphical Presentation Diagrammatical Presentation 4. Random numbers are a haphazard collection of certain numbers, arranged in a running manner to eliminate personal selection of unconscious bias in taking out the sample. How well the experiment test the hypothesis underlying it. Flashcards. If we take repeated samples from the same population or universe, the results obtained from one sample will differ to some extent from the results of another sample. Diagrams are better retained in the memory than statistical tables. This is done by calculating the standard error of difference between the two means. The bar chart is one of the most common methods of presenting data in a visual form. Researchers alter the situation by their presence. Charts, graphs, and images 4. The distance of a value (x) from the mean (X̅) of the curve in units of S.D. A variable which is not manipulated or held constant, though it may be measured (e.g., life events). Graphs; Descriptive statistics; Presenting qualitative data; Using GIS; 1. In this article, the techniques of data and information presentation in textual, tabular, and graphical forms are introduced. A bar chart consists of a set of bars whose heights are proportional to the frequencies that they represent. Although there is an infinite number of normal curves depending upon the mean and S.D., there is only standard normal curve. Instead of comparing the length of a bar, the areas of segments of a circle are compared. The best methods to use for presenting data vary depending on the type of information, volume and complexity of data and the audience. Tables are devices for presenting data simply from masses of statistical data. ii. �0"��Z� �j�UoB 1 Tabular Method Provides a more precise, systematic and orderly presentation of data in rows or columns. b���Hc�n5A���&E�~�i!MF"�D4هh� �d��d2�b�v�7M!���h6����h2��dMsI4�>h�,��\b.�f�x\|� �D+�D:F��F%�ۤ�n�A�HĈf�䛑���LP C��ЮdcW J��6�Jk����-���"�Ҧ���*� �¿���+�����6�Jk3��?6��.6�l�R-ʔgQ��H���bk��ŸR�E����t�.޵��P��J3��WK���RQ þ�g�[ja3b�2)��2)��;�&]l�E�)���J���@3�&]�E�6�NT��6ێo��t��EҤͪ�4��#v����/��%j=�mʕ�F$J���(y�/eITæ}8�HT�pʏ�pJ���M~t�e, ��� �E�`1r" �H���h�)�)�. on either side of the mean will include approximately 68% of the values in the distribution. �_3��?p���4A�[���I�j��`X�\Ͳ�1���T�,#/ �") �j�;��##m�YF: �e��\@�*�o�‘jݱD To obtain the mean, the individual observations are first added together, called summation or ‘S’ then divided by the number of observations. (d) Standard Error of Difference Between Proportions: Instead of means, sometimes one has to test the significance of difference between two proportions or ratios to find out if the difference between the two proportions or ratios have occurred by chance. Gerald W. Ouma ; 25 March 2010; 2 Data Presentation . Non parametric statistics use data which are not normally distributed (e.g., chi square test). Original data are called raw data. ), mail questionnaires (cheap and easy but low response rate, hence sample bias), self-rating questionnaires be answered inaccurately) and observer rated interview (structured, semi structured or informal, allow great flexibility and accuracy but are expensive and need training). kKv�5̙=�б�l���l�8��!�ݮ"�m��$BPm It is the most frequent item in series of observations. Graphs Your findings can be presented with a range of graphical and mapping techniques. Presentation of data with simple animation makes data powerful. In each of these groups he distinguished qualitative and quantitative methods. 5.Use callouts where required Using callouts is quite effective to draw the attention of your audience to multiple areas of your chart.

This is done by picking every 5th or 10th units at regular intervals. Kenny Thompson , 2 years ago 6 min read 2241 . A variable whose influence is kept constant by the experiment (e.g., other medications). Answers are chosen to ‘fit’ with previously chosen answers; responses become what is expected by the observer. Subject always tends either to agree or disagree with questions. Privacy Policy3. The shape of the curve will depend upon the mean and standard deviation which in turn will depend upon the number and nature of observation. 3. Let us see some ways in which we represent data in … The tools provided to automatically generate the images below are all very quick and easy to use. The purpose of putting results of research into graphs, charts and tables is two-fold. stream Introduction "Modern data graphics can do much more than simply substitute for small statistical tables. Primary data are those which are collected for the first time and are original in character 2. Variables are any constructs or events which research studies. %PDF-1.3 The standard normal deviate or Z is given by formula: When a large proportion of individuals or items or units have been studied we take a sample. The term “average” implies a value in the distribution, around which the other values are distributed. These scales are nominal, ordinal and numerical. Write. In this article we will discuss about the presentation methods of statistical data. ����M���U��m���0q���s0� �������-e W of the means is a measure of the sample error and is given by the formula σ√n which is called the standard error or the standard error of the mean. 3. The factors which influence the sampling error are size and variability of individual readings. Secondary data are those which have already been collected by someone else and which have been subjected to some statistical analysis Collection of Primary Data Primary data may be collected thru: 1.

It is defined as the difference between the highest and lowest figures in a given sample. Means is denoted by the sign X̅ (called “X bar”). Data, Presentation Methods, Presentation Methods of Statistical Data, Statistics. For smaller samples, the above formula tends to underestimate the standard deviation, and therefore needs correction i.e., use n-1 instead of n. The meaning of standard deviation can only be appreciated fully when we study it with reference to “normal curve”. When statistical data refer to geographic or administrative areas, it is presented either as “Shaded Maps” or “Dot Maps” according to suitability. �l�Ԩh�������揞�5+DΪ�ed Methods of Data Collection. High correlation between two halves of the same test. This will generate dimen­sions (e.g., psychotic neurotic). Line diagram are used to show the trend of events with the passage of time. This is done by assigning a number to each of the units (the individuals) in the sampling frame. %��������� Spell. Semi-tabular Method Data presentation methods- advantages and disadvatages. This technique provides the greatest number of possible samples. Created by. 3. The most common way of presentation of data is in the form of statements. It could be argued that this is another way in which qualitative research methods significantly differ from quantitative approaches. Audience and context 3. of 1.0 implies exact similarity and C.C. Subject tends to choose the middle response and shun extremes. It is an average of a different kind, which does not depend upon the total and number of items. Learn. This comes up, usually, in Chapter Four of the research project. Looks for the minimum number of dimensions which can be used to define a group.

It is obtained by joining the mid-points of the histogram blocks. When dealing with charts and graphs, having sufficient knowledge about frequency distribution, regular interval, axis label, frequency and other such terms is important. The sample is deliberately drawn in a systematic way so that each portion of the sample represents a corresponding strata of the universe. Data Graphics ; Data graphics are a good way to communicate important data in your reports. (c = number of columns, r = number of rows). Tabulation • Tabulation is the first step before the data is used for analysis or interpretation. Don’t worry. The antecedent condition manipulated by the experimenter (e.g., drug levels). To obtain the median, the data is first arranged in an ascending or descending order 0 of magnitude, and then the value of the middle observation is located.

With large amounts of data graphical presentation methods are often clearer to understand. • A table can be simple or complex, depending upon the number or measurement of single set or multiple sets of items. iii. Geography Data Presentation Techniques and Methods. value, find out a probability from published tables. It consists of a series of blocks. They are merely a way of presenting a set of numbers by the length of a bar. The mean, median and mode all coincide. There are essentially two types: 1. jkpgs. See the following slide with map showing data: The picture of the world map helps the audience get a visual context for the 4 pie charts. It occurs because data were gathered from a sample rather than from the entire population of concern. A source of error (e.g., age and sex imbalance). Wayne LaMorte, MD, PhD, MPH, Professor of Epidemiology, Boston University School of Public Health . Small pictures or symbols are used to present the data. In the latter, there exists really only one route from data to conclusions, and this is statistical analysis, alth… The bar chart can be simple, multiple or component type. (c) Standard Error of Difference Between Two Means: To compare the results between two groups (e.g., control group and experimental group), the difference between the means of two group is compared to indicate that the samples represent two different universe. will include 99.7% of the values. Before publishing your Articles on this site, please read the following pages: 1. These assess the meaning of the data e.g.,: Measures the statistical relationship between two sets of variables, without assuming that either is dependent or independent. It is a pictorial diagram of frequency distribution. Errors may occur due to inadequate calibrated instruments, due to observer variation as well as due to incomplete coverage achieved in examining the subjects selected and conceptual errors.

Categories on x-axis. High correlation between scores on the same test given on two occasions. 4 0 obj These reflect the particular theoretical perspectives or field within which the researcher is working. It is a smooth, bell shaped perfectly symmetrical curve based on an infinitely large number of observations. on either side of the mean will cover most of the values i.e., approximately 95% of the values. By this method, each unit is the sampling frame would have the same chance of being selected, but the number of possible samples is greatly reduced. Raw Data Data sheets are where the data are originally recorded. METHODS OF DATA PRESENTATION Textual Method Tabular Method Graphical Method METHODS OF PRESENTING In simple terms, it is defined as “Root-Means- Square-Deviation”. iii. Can only generate clusters not dimensions. If we have grouped data, the range is taken as the difference between the midpoints of the extreme categories. Tabulation can be in form of Simple Tables or Frequency distribution table (i.e., data is split into convenient groups). Welcome to PsychologyDiscussion.net!

The extent to which a test measures what it is designed to measure: Whether the test selects a representative sample of the total tests for that variable. I know – what a way to start an article about data. In the end, data should be presented in such a way that interpretation and analysis is made easy. Match. Every time you put up some numbers on the slide, think about adding a relevant picture to add clarity to your message. This is called to set confidence limits and find out level of significance. It's important to always keep the message in mind when visualising the data. It gives a mental picture of the central value. Data visualization is an interdisciplinary field that deals with the graphic representation of data.It is a particularly efficient way of communicating when the data is numerous as for example a Time Series.From an academic point of view, this representation can be considered as a mapping between the original data (usually numerical) and graphic elements (for example, lines or points in a chart). Visual communication 2. Data visualisation can have a negative impact on the viewer's ability to interpret the information, but that's due to a poorly created visualisation. First, one has to set up a hypothesis, called the Null Hypothesis that there was no difference between the findings of the two groups. C.C. Choosing the right presentation method such as use of pie chart, tabular form, line graph, histograms, regression line etc is vital. ��tQ��(_���eD�"���] i. The S.D. PLAY.

Common presentation modes including coding data, data analysis, drawing diagrams, boxplots, tables, pie charts and histograms. presentation methods, and learning to graph data one has collected oneself from one s own experiments is considerably more engaging and motivating than learning to graph using data that is given by the teacher. S.D. A very reliable test may have low validity precisely because its results do not change i.e., it does not measure true changes. The area between one S.D. Data Presentation Methods of Data Presentation Textual Data is The range is by far the simplest measure of dispersion. Measures relation­ship between two sets of variables but assumes that one is dependent and the other is independent. When data are more quantitative, such as- "7 out of 10 cells were dead", a table is the preferred form. The decision is based on the scale of measurement of the data. No general consensus exists amongst qualitative researchers concerning the process of data analysis. relevant forms of pictorial presentation or data display. ��֣� The normal distribu­tion or normal curve is an important concept in statistical theory. Sometimes in a data presentation, numbers can be cold and intimidating. In this, instead of means, proportions and its universe are used in a sample. STUDY. The methods used to present mathematical data vary widely. Story Time. The format for the presentation of data will depend on the target audience and the information that needs to be relayed. It has advantage that it can be used when more than two groups are to be compared. Our mission is to provide an online platform to help students to discuss anything and everything about Psychology.
