In a repeated measures design, each group member in an experiment is tested for multiple conditions over time or under different conditions. For example, a group of people with
Type II diabetes might be given medications to see if
it helps control their disease, and then they might be given nutritional counseling.
What is repeated measures design used for?
Repeated measures design can be used to
conduct an experiment when few participants are available
, conduct an experiment more efficiently, or to study changes in participants’ behavior over time.
What is repeated measure design in psychology?
Repeated Measures design is
an experimental design where the same participants take part in each condition of the independent variable
. This means that each condition of the experiment includes the same group of participants. Repeated Measures design is also known as within groups, or within-subjects design.
When should repeated measures be used psychology?
In the repeated measure design all the participants serve as their own control because they are involved in the experiment and control groups. The repeated measure design is only to be used
when the two sets of scores represent measures of exactly the same thing
.
What is a repeated measures design quizlet?
repeated measures designs.
Research designs in which each subject participates in all conditions of the experiment
(ie, measurement is repeated on the same subject. sensitivity.
What are two advantages to a repeated measures design?
More
statistical power
: Repeated measures designs can be very powerful because they control for factors that cause variability between subjects. Fewer subjects: Thanks to the greater statistical power, a repeated measures design can use fewer subjects to detect a desired effect size.
What do you mean by repeated design?
Repeated measures design is
a research design that involves multiple measures of the same variable taken on the same or matched subjects
either under different conditions or over two or more time periods. For instance, repeated measurements are collected in a longitudinal study in which change over time is assessed.
What is the major confound facing repeated measures design?
A major advantage of a repeated measures design is
that subjects are used as their own control
because each subject is a member of the control group and the experimental group. … The greatest disadvantage with repeated measures designs is possible carryover effects.
What is repeated measures factorial design?
The repeated-measures factorial design is
a quantitative method for exploring the way multiple variables interact on a single variable for the same person
(Field, 2009). … The second is repeated measures: each participant is exposed to all combinations; that is, each independent variable at each level (Cohen, 2008).
How do you control order effects in psychology?
Carryover and interference effects can be reduced by increasing the amount of time between conditions. Researchers also reduce order effects by systematically varying the order of conditions so that each condition is presented equally often in each ordinal position. This procedure is known as
counterbalancing
.
What is CORR among repeated measures?
Repeated measures correlation (rmcorr) is
a statistical technique for determining the common within-individual association for paired measures assessed on two or more occasions for multiple individuals
. … Rmcorr estimates the common regression slope, the association shared among individuals.
What is meant by repeated measures?
A repeated-measures design is
one in which multiple, or repeated, measurements are made on each experimental unit
. … The repeated assessments might be measured under different experimental conditions. Repeated measurements on the same experimental unit can also be taken at a point in time.
Which of the following is an advantage of using a repeated measures design over an independent groups design?
Repeated measures design has
greater ability to detect an effect of the independent variable
.
Which of the following is a drawback of the matched pairs design group of answer choices?
Which of the following is a drawback of the matched pairs design?
It can be costly and time-consuming
. Dante would like to conduct a study in which participants taste five different brands of honey and decide which one they like best.
When repeated measures are used which assumption is violated?
Unfortunately, repeated measures ANOVAs are particularly susceptible to violating the
assumption of sphericity
, which causes the test to become too liberal (i.e., leads to an increase in the Type I error rate; that is, the likelihood of detecting a statistically significant result when there isn’t one).
