What is independent measure?

An independent measures design is a research method in which multiple experimental groups are used and participants are only in one group. Each participant is only in one condition of the independent variable during the experiment. An example would be a drug trial for a new pharmaceutical.

What is an independent sample design?

An independent samples design is a true experiment characterized by random assignment of participants to conditions and manipulation of the independent variable. In conjunction with the use of control groups, this design permits cause–effect conclusions and results in fewer alternative interpretations of the data.

What is dependent measures design?

A within-subjects design is also called a dependent groups or repeated measures design because researchers compare related measures from the same participants between different conditions. All longitudinal studies use within-subjects designs to assess changes within the same individuals over time.

What are the disadvantages of independent measures?

Disadvantages

researcher cannot control the effects of participant variables (i.e. different characteristics or abilities of each participant). This would cause a confounding variable.
needs more design than the Repeated Measures Design in order to end up with the same amount of data.

What does an independent measures study use?

An independent-measures study uses a separate group of participants to represent each of the populations or treatment conditions being compared. The estimated standard error measures how much difference is expected, on average, between a sample mean difference and the population mean difference.

Why is an independent samples design good?

Advantage – Reduces demand characteristics: An independent samples design makes it less likely that participants will guess the hypothesis of the experiment. If participants complete the experiment twice, they might guess the purpose of the experiment, and change their behavior accordingly.

What is an example of an experimental design?

This type of experimental design is sometimes called independent measures design because each participant is assigned to only one treatment group. For example, you might be testing a new depression medication: one group receives the actual medication and the other receives a placebo. Group 2 (Medication 2).

What are the types of experimental design?

Three types of experimental designs are commonly used:

Independent Measures: Independent Measures:
Repeated Measures: Repeated Measures:
Matched Pairs: Matched Pairs:

What are the examples of experimental design?

What is basic experimental design?

Experimental design refers to how participants are allocated to the different groups in an experiment. Types of design include repeated measures, independent groups, and matched pairs designs. The researcher must decide how he/she will allocate their sample to the different experimental groups.
