A researcher has taken tissue cultures from 25 subjects. Each culture is divided into in half and a treatment is applied to one of the halves chosen at random. The other half is used as a control. After determining the percentage change in the sizes of all culture sections, the researcher calculates the standard error for the treatment minus control difference using both the paired t-test analysis and independent sample (see ch2) t-test analysis. Finding that the paired t-analysis gives a slightly larger standard error, the researcher decides to use the results from the (non paired) independent t-test analysis. Is this legitimate? Select the best answer.
