Question

learning target 2: i can identify and define variables. complete all levels. level: basic (ib 2 - 5) 2. remember the \1 - 100\ game we played a few weeks ago? we could think of that game as an experiment with 2 variables: the number of people in a group and how many numbers the group found. a. which variable is independent? explain how you know. b. which variable is dependent? explain how you know. remember: the more people in the group, the more #s we could find.

Explanation:

In an experiment, the independent variable is the one that is manipulated or changed by the researcher. The dependent variable is the one that is measured and is affected by the independent variable. In the "1 - 100" game experiment, the number of people in a group can be controlled or changed (e.g., forming groups of different sizes). The number of numbers found by the group depends on the number of people in the group. So, the number of people in a group is the independent variable because it can be varied, and the number of numbers the group found is the dependent variable as it is affected by the number of people.

Answer:

a. The independent variable is the number of people in a group. We know this because we can change the size of the group (e.g., have groups with different numbers of participants).
b. The dependent variable is the number of numbers the group found. We know this because the amount of numbers found likely depends on how many people are in the group; more people may lead to more numbers being found.
