Question

In data collection, what are three important constants, also known as controlled variables?

a) Independent variable, range, and outliers.
b) Dependent variable, standard deviation, and mean.
c) Control group, sample size, and conditions.
d) Correlation, causation, and extrapolation.

Answer 1

In data collection, the three important constants, also known as controlled variables, are the control group, sample size, and conditions.

Step-by-step explanation:

In data collection, the three important constants, also known as controlled variables, are:

1. Control group: A group in an experiment that serves as a basis for comparison and controls for chance factors that might influence the results of the study by holding such factors constant across groups. This ensures that the experimental manipulation is the only difference between groups.
2. Sample size: The number of experimental units or individuals in a study. It is important to have an appropriate sample size to ensure the accuracy and reliability of the results.
3. Conditions: The specific conditions or settings under which the experiment is conducted. Keeping these conditions constant across the experimental and control groups helps to ensure that any observed differences are due to the independent variable and not other factors.
