Question

The table shows the number of flowers in four bouquets and the total cost of each bouquet.





What is the correlation coefficient for the data in the table?


–0.57

–0.28

0.28

0.57

Answer 1

we know that

The correlation coefficient is a number between $-1$ and $+1$ that represent the linear dependence of two variables or sets of data

Using the function CORREL in a excel tool, calculate the correlation coefficient (r)

see the attached table

the correlation coefficient for the data in the table is equal to $0.28$

therefore

the answer is

$0.28$

Answer 2

It should be noted that in the table, the correlation coefficient for the data is C. 0.28.

Correlation coefficient.

It should be noted that a correlation coefficient simply means the number that's between -1 and +1.

It represents the linear dependence between the two variables. In this case, the correlation coefficient for the data is 0.28.
