Unformatted text preview: distributions can be described in simple sentences. For instance, the gender distribution of a sample study may be described as “The sample data represents 58% by males and 42% of the sample are females.” Tow-Way Table: Distributions in terms of two or more variables and the relationship between the two variables are show in two-way table. The categories of one variable are presented one below another, on the left margin of the table those of another variable at the upper part of the table, one by the side of another. The cells represent particular combination of both variables. To compare the distributions of cases, raw numbers are converted into percentages based on the number of cases in each category. (Table 10.2) illustrate two-way tables.

Here, special care has been taken as to how the percentages are calculated, either on a horizontal representation of data or as vertical representation of data. Sometimes, the table heading itself provides a meaning as to the method of representation in the two-way table.

In additions to tabular forms, graphic presentation involves use of graphics, charts and other pictorial devices such as diagrams. These forms and devices reduce large masses of statistical data to a...
