Why is median not defined??? Isn’t it Lenovo?

Hello,

it is because the categories in the Pie chart are NOMINAL VARIABLES.

They are NOT ORDINAL VARIABLES.

Median is only defined for ORDINAL VARIABLES when it comes to Categorical Data.

Hope this helps.

Abhinav.

Hi,

For finding median, we need to arrange the data in ascending order but variable with nominal scale of measurement does not contain any order. That's why median is not defined for nominal scale.
