3) Ronald, a marketing consultant, is hired by a restaurant chain that wants to open a new location. To help with this, Ronald asks residents in multiple different neighbourhoods to indicate how interested they would be in a new restaurant, using a five-point Likert scale.

Ronald finds that the average rating on his scale for one neighbourhood is 2.2 out of 5; whereas the average rating for a different neighbourhood is 4.4 out of 5. Ronald happily tells his client that the second neighbourhood is twice as interested in having a new restaurant. Why should the client be doubtful about Ronald's conclusion?

O a. He failed to employ a pre-test versus post-test approach.

O b. He did not use a consensus scale to measure the level of

agreement between different residents.

O c.

He cannot guarantee that his Likert scale values functioned like real numbers.

O d. He did not use a consensus scale to measure the level of

agreement between different residents.

6) A researcher conducts a cross-sectional study, and concludes that their two variables seem to be related.
