Question

A researcher recruited 55 adults and tested their ability to remember a list of words. For each participant, the researcher counted the number of words correctly recalled and recorded their age (in years).

HYPOTHESIS

The research hypothesis is that age is related to memory performance.

This hypothesis is:

a. directional

b. non-directional

RESULTS

Suppose the researcher calculated a correlation of r = -0.04 between age and memory performance.

APA style: (r(53)=-0.04, p>0.05)

CONCLUSION

This result: is/is not statistically significant

we: reject/fail to reject the null hypothesis that there is no relationship between (predictor): age/memory performance and (outcome): age/memory performance (r(53)=-0.04, p>0.05). There is: statistically significnat evidence/no evidence that these two variables are related to each other.

Explanation / Answer

This hypothesis is:

b. non- directional

It is not a one tailed test.

for, r=-0.04 and df = 53,

p value = 0.776

This result is not statistically significant.

We fail to reject the null hypothesis that there is no relationship between age and memory performance. There is no evidence that these two variables are related to each other.
