Question

Identify the correct statement about correlations:

a) There is a correlation of 0.54 between the position a football player plays and their weight.
b) The correlation between planting rate and yield of corn was found to be r.
c) There is a correlation of 0.54 between the position a football player plays and their weight, indicating a moderate relationship.
d) Correlation is not an appropriate measure for these types of variables.

Answer 1

The correct statement about correlations is option c) There is a correlation of 0.54 between the position a football player plays and their weight, indicating a moderate relationship.

Step-by-step explanation:

The correct statement about correlations is option c) There is a correlation of 0.54 between the position a football player plays and their weight, indicating a moderate relationship.

Correlation coefficients, denoted as 'r', range from -1 to 1. A positive correlation coefficient indicates a positive relationship between variables, meaning that as one variable increases, the other variable also tends to increase. In this case, a correlation of 0.54 suggests a moderate positive relationship between the position a football player plays and their weight.

Option a) is not correct as it states that the correlation coefficient is 0.54, but it does not specify the nature of the relationship. Option b) is incorrect as it does not provide any specific value for the correlation coefficient. Option d) is also incorrect as correlation is an appropriate measure for studying the relationship between variables.
