Question

A researcher recruited 40 adults between the ages of 40 and 80 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 negatively related to memory performance.

This hypothesis is: directional/non-directional

RESULTS

Suppose the researcher calculated a correlation of r = -0.24 between age and memory performance.

APA style: (r(48)= -0.24, p<0.05)

CONCLUSION

This result is/is not statistically significant

We fail to reject/reject the null hypothesis that there is no relationship between (predictor): age/memory performance and (outcome): age/memory performance (r(53)=0.395, p<0.01). As age increases,: memory performance decresases/so does memory performance

Explanation / Answer

here This hypothesis is: directional (as we are looking if it is negatively related

as p value is not lower than 0.05 level

as This result is not statistically significant

We fail to reject  the null hypothesis

there is no relationship between age and  memory performance
