A researcher carried out an experiment to investigate whether drinking coffee improves concentration levels. The task involved completing a driving hazard perception test which recorded the number hazards spotted. Participants completed the task once when having not drunk any caffeine for 24 hours and again 30 minutes after drinking a cup of strong coffee.
What stats test should she use?
Mann-Whitney U test
Wilcoxon signed ranks test
Binomial sign test
Chi square test
A Mann-Whitney U test has been carried out on a study investigating whether young boys (n=10) and girls (n=8) differ in their self-ratings of strength. The results showed a calculated value of 16 and the critical value for a 2-tailed test at the 0.05 level of significance is 17.
What should the researcher do?
Accept the null hypothesis
Reject the null hypothesis
Reject both the null and alternative hypotheses
A researcher carried out an observation in a supermarket observing whether there is a difference between males and females in the number of fruit and vegetables they buy. She did this by pretending to be another shopper ticking items of her shopping list. What type of observation is this?
