1. Find the medians of the following data sets: {8, 7, 3, 5, 3}; {7, 8, 3, 6, 10, 10}.
2. Here is a dataset for mortality due to work-related injuries among African American women in the United States during 1997: {15-24 years (9); 25-34 years (12); 35-44 years (15); 45-54 years (7); 55-64 years (5)}.
a. Identify the modal class.
b. Calculate the estimated median.
c. Assume that the data are for a finite population and compute the variance.
d. Assume the data are for a sample and compute the variance.
3. A sample of data was selected from a population: {195, 179, 205, 213, 179, 216, 185, 211}.
a. Use the deviation score method and the calculation formula to calculate variance and standard deviations.
b. How do the results for the two methods compare with one another? How would you account for discrepancies between the results obtained?
