Question:

How to check the frequency distribution of a categorical variable?

Answer:

The frequency distribution of a categorical variable can be checked using the table function in R language. Table () function calculates the count of each categories of a categorical variable.

gender=factor(c(“M”,”F”,”M”,”F”,”F”,”F”))

table(sex)

Output of the above R Code –

Gender

F  M

4  2

Programmers can also calculate the % of values for each categorical group by storing the output in a dataframe and applying the column percent function as shown below -

t = data.frame(table(gender))
t$percent= round(t$Freq / sum(t$Freq)*100,2)

Gender Frequency Percent
F 4 66.67
M 2 33.33
