What is an example of an independent measures design?
What is an example of an independent measures design?
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 measures experimental design?
Independent measures design, also known as between-groups, is an experimental design where different participants are used in each condition of the independent variable. This means that each condition of the experiment includes a different group of participants.
How many participants are needed for an independent measures design?
a. An independent-measures design would require two separate samples, each with 10 subjects, for a total of 20 subjects.
What are the different types of experimental design?
There are three types: 1. Independent measures / between-groups: Different participants are used in each condition of the independent variable. 2. Repeated measures /within-groups: The same participants take part in each condition of the independent variable. 3.
Which is an independent variable in experimental design?
The independent variable is the amount of nutrients added to the crop field. The dependent variable is the biomass of the crops at harvest time. Defining your variables, and deciding how you will manipulate and measure them, is an important part of experimental design .
Where can I get an experimental design template?
Download the Experimental Design Template. You and your partner will each turn in a digital write-up of your experiment. You are responsible for completing all sections of the template. This template is similar to the one you will use for the science fair.
Which is better, repeated measures or experimental design?
Con: More people are needed than with the repeated measures design (i.e., more time consuming). Pro: Avoids order effects (such as practice or fatigue) as people participate in one condition only.
