Any conclusion drawn for the t-test statistical process is only as good as the research question asked and the null
hypothesis formulated. T-tests are only used for two sample groups, either on a pre post-test basis or between two
samples (independent or dependent). The t-test is optimized to deal with small sample numbers which is often the
case with managers in any business. When samples are excessively large the t test becomes difficult to manage due
to the mathematical calculations involved.
Calculate the “t” value for independent groups for the following data using the formula
presented in the module. Check the accuracy of your calculations. Using the raw
measurement data presented above, determine whether or not there exists a
statistically significant difference between the salaries of female and male human
resource managers using the appropriate t-test. Develop a research question, testable
hypothesis, confidence level, and degrees of freedom. Draw the appropriate
conclusions with respect to female and male HR salary levels. Report the required “t”
critical values based on the degrees of...
