Question

College students in a cognitive mapping study are asked to use a direction finder to point accurately to three unseen locations that differ in distance from the lab. One is a nearby campus location, one is a nearby city, and the third is a distant city. Half of the participants perform the task in a windowless room with a compass indicating the direction of north. The remaining participants perform the task in the same room without a compass. A. the independent variable(s) – all of them! a. the levels of the IV b. the nature of each IV (between-subjects, within-subjects) c. the type of IV (manipulated or subject variable) B. the dependent variables(s)

Answer 1

independent variable -

IV1 - use of compass with north orientation

levels of IV 1 - compass present , compass absent

nature - between subjects

type - manipulated

IV2 - target loacation

levels of IV 2 - campus, nearby city, distant city

nature - within subjects

type - manipulated

Dependent Variable - accuracy of finding the locations

Thr study is a 2×3 mixed factorial design with 2 independent variables, Independent variables are those variables which vary on their own, they have a causal effect on another variable called dependent variable.

When there are more than 1 independent variable the study designs can be

• within group - the results are compared between participants of 2 groups.
• between group - the results are compared for the dame group compared in different test situations.
