1. Calculate the mean, median, and mode for "Age" (with SPSS).
2. Calculate measures of dispersion for "Age" (with SPSS).
3. Calculate Skewness and Kurtosis for "Income" (with SPSS). Is this variable skewed? If so, what kind of skew?
4. Prepare a frequency distribution for the data of "number of past jobs." Plot it (bar chart).
5. Given the provided income distribution (and assuming normality), what would be the z-score for someone who earns $40,000/year? $100,000/year?
SLP Assignment Expectations
1. Answer all questions with clarity and depth. Show your critical thinking ability.
2. Show necessary reasoning.
3. You do not need to write an essay for SLP assignment; answering the questions is sufficient.
