Describe what the standard deviation tells us about the population data. 3. Describe the skewness of your "population" data of 50 and explain how the mean and median are related to that. 4. Compare the overall measures of central tendency between your "population" of 50 and your "sample" of 25. Is it a "good" sample? Do you think it would be a better or worse sample if you did 5 instead of 25? 5. What proportion of your population does your sample represent? In other words, what percentage of your population is represented by your sample? 6. Suppose you repeated that sampling procedure 50 times. Do you think it is less likely or more likely you would get close to your population mean every time?
