Given:

A data set is a symmetric distribution.

Every value in the data set is doubled.

Concept used:

Bivariate joint frequency distribution are contingency table.

The total row and total column of the marginal distribution while the body of the table is the joint frequencies

Calculation:

The height will be doubled but will still be symmetric.

Each value in a numerical data set is multiplied by a real number k

Where k > 0

The measures of center and variation is founded by multiplying the original measures by k

Therefore,

This is also dobled.
