Suppose that you are interested in studying the level of education (schooling) of
individuals. Please complete the steps below:
1. Raise a research question based on the above;
2. Measure "the level of education" of as a variable;
3. List at least three variables that you think affect the level of education of an
individual, AND explain how you measure each variable;
4. Explain the level of measurement for the four variables in Step 2 and 3;
5. Explain the unit of analysis in the study;
6. Explain the dependent and independent variables.
Question B
Data are collected on the educational level of urban residents over 24 years of
age in cities in 2016 and 2021 The following data are for 25 cities in 2011 and
2021; each number represents the percentage of urban residents over 24 years
of age in a city WITHOUT an university education at the time the data were
collected.
(1) 2011
66, 57, 56, 48, 48, 48, 42, 41, 41, 40, 39, 35, 34, 33, 32, 31, 31, 30, 30, 29, 26,
24, 24, 21, 20
(2) 2021
50, 46, 41, 40, 40, 40, 39, 39, 33, 31, 30, 29, 28, 26, 25, 25, 24, 24, 23, 22, 22,
20, 19, 18, 17
Please complete the following:
1. Construct a frequency distribution table for data pertaining to (1) and (2).
2. Calculate the median, mean, variance, and standard deviation for data in
(1) and then data in (2), and please show procedures of each calculation.
3. Compare data in (1) and (2) based on Step 2, and explain the difference.
4. Construct a histogram from the frequency distribution in Step 1.
