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
