What are the independent and dependent variables for the following examples? What statistical test would you use for each of the following scenarios? Do the best you can based on the lectures. Sally wants to examine whether there is a difference in muscular strength between participants who engaged in an 8-week resistance training program and participants who engaged in an 8-week endurance training program. The participants only took part in one of the 8 week programs, not both. What test would she use to determine whether the differences in muscular strength are significant? Adrian examined the calcium intake in three groups of individuals with varying levels of bone mineral density. Group 1 had low bone mineral density, Group 2 had moderate levels of bone mineral density and Group 3 had high levels of bone mineral density. In order to determine the mean differences between the groups on calcium intake what statistical test would be best used in this scenario? Calvin wants to know whether gender and training have an effect on blood pressure in avid vegans. In his study he has four groups, trained female vegans, untrained female vegans, trained male vegans, untrained male vegans. He measures blood pressure in each group over a 24-hour period. What statistical test would be he use to help him determine whether gender and training impact blood pressure? Sarah wants to know how gender impacts heart rate recovery after a maximal exercise test. In order to test this, she has both male and female athletes come into her lab and she measures both resting heart rate before the exercise test and heart rate immediately, 10 minutes, 20 minutes and 30 minutes following the exercise test. In order for her to determine whether heart rate differs pre-post exercise between males and females what statistical test might she use? Dahlia is interested in how depression impacts willingness to exercise and go to the gym. In order to do this, she has to have a large sample size, so she decides to send out a survey to all college students at SUNY Cortland. Once she receives 80% of the surveys back from the students she begins to record the data. Because of the responses to her questionnaires, she will not have normally distributed data. In this case, what might be the best statistical test to use to determine whether going to the gym/willingness to exercise is impacted by depression? Spencer would like to study how gender and PTSD in veterans impacts risk for dementia. In order to study this, he will need four groups and all four groups will have to be veterans. Females with PTSD, females without PTSD, Males with PTSD, Males without PTSD. What would be the best statistical test to examine how gender and PTSD status impact risk for dementia in this cohort?
