Let me help you study...

1.  A research decides she wants to study new immigrants to Canada and their experiences in the Canadian labour force.  From this general topic, there are two ‘concepts’ she has to defined.  What are they?

2. She decides to do a quantitative study of the above topic. After she has decided on her concepts, WHAT does she need to do to measure them?

3. The researcher is going to do a survey on the above topic. She needs to construct good survey items. What are some items she could ask people to determine their immigrant status? Include all categories of the variable.

4. The researcher made a variable for immigrant status and found that other researchers thought that it looked like a pretty good way of measuring the concept. What kind of validity does that demonstrate?

5. She also found her variable was pretty close to how another famous researcher was measuring immigrant status. What kind of validity does that demonstrate?

6. The measure also seems to fit pretty close with its conceptual definition. What kind of validity does that demonstrate?

7. The researcher walks around York university and asks random people her survey questions.  What kind of sampling is that?  What is a disadvantage of that kind of sampling?

8. If the researcher did a simple random sample of York university students, she would need a list of all elements of her population, which is known as a _______________.  Where could she get such a list?

9. After getting some surveys completed, the researcher has some data to analyze. She wants to get some measures of central tendency. What measures of central tendency can she obtain for a variable that assesses whether someone is an immigrant or not?

10. She also asked respondents how many hours per week they worked and obtained data on the number of hours they spent in paid employment. What measures of central tendency could she examine there?


11. She found that immigrants had an average of 30 hours per week in paid employment, while non-immigrants has 32. The standard deviation for immigrants was 15, but for non-immigrants it was 2. What does this mean roughly?
