Let us learn about frequency distribution table
Frequency distribution table is a tabulation of the values that 1 or more variables take in a sample. Each entry in the frequency distribution table contains the frequency or count of the occurrences of values within a particular group or interval, & in this way the table summarizes the distribution of values in the sample.
Frequency distribution table is used to rank the disorganized data from the highest to the lowest. A frequency distribution table is an organized tabulation of the number of individual scores located in each category on the scale of measurement. Frequency distribution table contains at least 2 columns – 1 for the score categories (X) & another for the frequencies (f).
Frequency distribution table can be represented in a number of ways.
Group frequency table as Regular frequency table
Group frequency graph as Polygon; The bar graph; Pie Chart; Histogram
The bar graph is used only when the data or measurements are from a nominal or an ordinal scale. Histogram - Interval or Ratio data, Polygon - Interval or Ratio data
Group frequency distribution table is used when the original scale of measurement consists of more categories which can be listed in a regular table, 20 or more categories is generally considered too much. The easiest & the most complete way to present a set of N= 7 scores is to list each individual score.
