Conclusion
Following completion of this free OpenLearn course, Medical statistics, as well as being able to ‘calculate the statistics’ you should also find that your skills in interpreting results are improving.
You should now be able to:
- estimate relative risks and odds ratios using data from a cohort study
- estimate odds ratios using data from a case-control study
- calculate and interpret confidence intervals for the relative risk and odds ratio
- test for no association using the chi-squared test
- interpret the results of a chi-squared test for no association and Fisher’s exact test.
