Please this is for statistical analyst in the house. Please I have a few questions as regards the SPSS 1. In a one sample t-test, when the test value is not given, how do we set the test value? Is it okay to use the population mean and the test value? 2. What statistical procedure is best for testing hypothesis of the nature: a). HO: There is no significant treatment by sex by location interaction effect at retention b). HO: There is no significant treatment by sex by location by age interaction effect at post test.
