Question

What are the statistics used to summarize categorical data?

Answer 1

Statistics used to summarize data:

1. Frequency Table: Calculating counts for each combination of a categorical variable. For e.g. Count of female and male in the data.

2. Proportion: Calculate the frequency of each combination of categorical variable and divide each with total frequency to get the proportion of each combination of a categorical variable. e.g. Calculation the proportion of Married, Single and Widowed in marital status variable.

3. Contingency Table/Marginals : Calculate marginal frequencies and represent it as a table which shows total counts / percentages for marginal frequencies.

e.g.            F          M

Married      x₁₁       x₁₂

Single       x₂₁       x₂₂

Widowed   x₃₁       x₃₂

_{4: Visualization: Make bar graphs or pie charts for the categorical variable. e.g. Bar graph for total count of population in each state of India or Pie chart for what proportion of total population lives in each state of India.}
