QUESTION 1
Before Andrea can formulate the survey and select the respondents for the focus group, she needs
to define the research problem and ensure that this relates to a specific population.
ANSWER: True
QUESTION 2
Andrea decides that she needs to gather participants for the focus group. Using customer
information sheets, Andrea has a list of 100 customers that are on record for purchasing from The
Grape Vine. Andrea assigns each customer a number, ranging from 1 to 100. She decides to
separate the customers into age categories (18-45; 45 and over), so that the sample of 10 can be
taken equally from each age category (5 and 5).

them down on a piece of paper.

45, female under 45 and female over 45.

QUESTION 5
Match the following statement or action to the correct sampling technique:
a. Andrea sends an email to research participants calling for volunteers to participate in the
focus group
