    ANOVA question

    If I have 20 male subjects, all given the same treatment and measured at predose, 1, 2, and 3 days postdose....is it acceptable to treat these all as different groups? ie. perform an anova using the different timepoints as different groups? (All assumptions being made). Also to conduct post...

    Comparing one group over 4 timepoints?

    So would it be best to do multiple t tests and correct for false discovery rate? Or wilcoxin?

    Should I use Chi squares?

    Data was compiled based on demographics and medical records that assured the samples were comparable. Same time in the disease state so no lead time bias. We don’t know the time of death, just whether they survived or not and want to know if the extra time it takes to run the older tests has...

    Should I use Chi squares?

    Correction: there was 100 for the older method and 176 for the newer. 16 survived in the older methods and 34 survived in the newer.

    Should I use Chi squares?

    I want to see how old pancreatic cancer detection methods (slow and invasive) and newer (faster less invasive) have an effect on survival. I simply have data for the number of people that survived from pancreatic cancer in 100 people from each method. Needs to be simple analysis.

    Comparing one group over 4 timepoints?

    What test and posttest would be most appropriate for a sample size of 10 assuming equal variances and normal distribution at a baseline and 3 timepoints? I need to compare each timepoint against the baseline. The parameter is body temperature.

    T tests?

    Hi. I have 1 group of 10 people with blood pressure taken at a baseline and at 2 timepoints after given a drug. I need to compare each timepoint against a baseline. Should I use RM anova or multiple t tests?

    Simple anova?

    Increase. I actually cut it down to every hour for 5 hours.

    What tests to use?

    have two groups of people, each group taking a different blood pressure medication. Blood pressure is taken daily for 30 days. Medication 1 works better than 2, as is shown by a lower 10 mmHg difference on day one. It is also more stable so blood pressure remained the same over time. Patients...
