Question

We have weight and height for 8 people, the data is given below:

Weight (kg): 45, 52, 56, 62, 70, 53, 72, 51
Height1(cm): 161, 165, 168, 172, 175, 163, 178, 162

Height2 (m): 1.61, 1.65, 1.68, 1.72, 1.75, 1.63, 1.78, 1.62

(a) Find the correlation between weight (kg) and Height (cm)

(b) Find the correlation between weight (kg) and Height (m)

C) Do you get the same correlation for both (a) and (b)?

D) Without calculation, just think about the correlation between weight which we now
convert to pounds and height (cm), what is the correlation? And why?

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
