Question

A researcher is interested in the relationship between concussions and short-term memory loss. To explore this relationship, the researcher collects data on the number of concussions and number of words recalled on a memory test.

Assume SP = -34       SS_concussions =    58        SS_{number of words recalled} = 27

Interpret the Pearson correlation coefficient between concussions and number of words recalled in terms of the strength and direction of the relationship:

Answer 1

The Pearson correlation coefficient between concussions and number of words recalled is -0.02

the two variables are negatively correlated.

so direction is negitive.

and correlation coefficeint is near to 0 . it is having strength is week.

in terms of the strength and direction of the relationship:

The correlation between the concussions and number of words recalled is negatively associated & the week relationship between them.
