'Analysis of data'

Statistical test chosen:

Pearson's R

Scatter plot:

To find out how strong is the relationship between the arm span and the height.

This is the scatter plot for the arm span and the height of respondents.

The table shows Pearson's R is 0.623, P less than 0.05.

The Pearson's R value falls under 0.6-0.8 which is equals to strong relationship.

The P is less than 0.05 thus we reject the null hypothesis.

Therefore, there is a relationship between the arm span and the height.
