You are interested in the effect of room temperature on how well students do at memorizing a list of unrelated words. You randomly assign half of the student participants to a cool room and half to a warm room. You then give each group the list of words. After showing them the list, you have them write down as many words as they can remember (a free-recall task). What is the independent variable? What is the dependent variable?

Answer #1

This is an experimental research design where randomization has been used to form two groups. Therefore, this is a two group randomized experimental design to assess the effect of room temperature on learning.

The independent variable is the one which is manipulated by the researcher and its effect of this manipulation is seen on the dependent variable. The independent variable in the given study is thus, room temperature and the dependent variable is learning.

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 company claims to have created a new study pill that increases concentration and alertness. You design a research study to test whether students are better at learning new information after taking the pill. First, you post flyers around campus advertising your study. You make a list of everyone who responds to your flyer and randomly assign each student to either a pill or no pill group. You tell n = 10 participants to come to your lab at 8:00...

As you saw from the lab PowerPoint slides last week, you will be doing a research study looking at ‘Aggression Priming” for your first paper. For this week’s discussion, I want you to discuss with your group what you think this study is about. What is the hypothesis? What theory does it come from? What do you predict will happen (do you expect something different than the hypothesis in the researcher instructions? If so, what and why?)? Do you think...

Research Scenario: A developmental psychologist wants to study the effect of instructional type on learning of the alphabet. She randomly selects a sample of 20 students at the local preschool and assigns them to two groups, a “Testing Effect” group who takes daily tests of recall on the alphabet (n=10) and a “Meaningful to Self” group who comes up with things they like that start with each letter of the alphabet and discuss them in groups (n=10). After one week...

A psychologist is interested in the effect of auditory distractors on performance in hand-eye coordination tasks. She gathers a group of subjects and randomly divides them into four groups. All of the subjects then play a video game requiring substantial ongoing hand-eye coordination. The game internally scores the subject’s hand-eye coordination performance but does not adjust its difficulty based on subject performance. At the end of the testing period, the software produces an overall hand-eye coordination score for that subject...

The table below gives the number of hours spent unsupervised each day as well as the overall grade averages for seven randomly selected middle school students. Using this data, consider the equation of the regression line, yˆ=b0+b1xy^=b0+b1x, for predicting the overall grade average for a middle school student based on the number of hours spent unsupervised each day. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would...
