A marketing researcher wants to put together four focus groups of 18-24 year-old males who are heavy downloaders of music (defined as downloading 50 songs per month). Instead of asking people at a shopping mall whether they download music from the Internet, he finds one person in the target market who qualifies, and then asks that person to suggest the names of two other males between the ages of 18-24 who download music. The researcher will invite those two to participate in the focus group, and then they are each asked to suggest two others similar to themselves to participate in the focus group study. This procedure describes a ____.
a. stepwise sample
b. judgment sample
c. area sample
d. snowball sample
