Random assigment can be described as a research method:
A used to balance the independent and dependent variable
B no longer used because of its unpredictability
C increasing the likelihood that experimental group and control group will be different
Cused to balance the control and experimental groups
I THINK CORRECT ANSWER IS A OR D
Random assignment is used to make the experimental groups more like the population they represent. D is the answer. A makes no sense
Are these people a worker in a farm? Which is the Independent and Dependent variable and Control group
The correct answer is indeed D: used to balance the control and experimental groups.
Random assignment is a research method used in experimental studies to ensure that participants have an equal chance of being assigned to either the control group or the experimental group. It is commonly used to balance the groups and minimize potential biases in the study.
To implement random assignment, researchers typically use a randomization procedure, such as using a random number generator or flipping a coin. This random allocation method helps to reduce the likelihood of systematic differences between the groups, allowing researchers to attribute any observed differences in outcome variables to the independent variable being studied.
Options A and B are incorrect. Random assignment is not intended to primarily balance the independent and dependent variables (A), but rather the control and experimental groups. Additionally, option B is not accurate, as random assignment is still widely used in scientific research today, despite its unpredictability.
Therefore, the correct answer is D: random assignment is used to balance the control and experimental groups.
