What is an experiment?
An there's factor (independent variable) that can be manipulated to observe the effect of behavior or mental process (dependent variable).

-0.67
What is a Longitudinal study?
Retesting the same people overtime
What is a Correlational Study?
( the two correlate)
The participants had the rights to leave. Which guideline did the research follow?
Withdrawal rights.
What is the computed measure of how much score vary around the mean?
Standard deviation
Describe the meaning of the standard deviation of 5.67 for the age of participants
The Standard deviation of 5.67 means the age gab between participant is 5.57 years
What is a Cross sectional study?
Study comparing people of different age at the same point of time

Mean - 9.66
Median - 10
Mode - 12
What is a Meta-analysis?

What the Control group v.s a Experimental group?
Control group does receive a 'placebo'. The group is left alone
Experimental Group is the one you can manipulate to compare with control group.
The research ensure participants weren't emotional, physical, and psychological harmed in the research.
Protection from harm.
What is significant difference? A nd what does it mean if p(probability value) is lessor or greater than 5.
Explains that if the result is explainable/there is a cause or relationship.
Less than 5 means there is a significant difference
Greater than 5 means no significant difference
The researcher wants to find the change of anxiety level by randomly assigning either a new medication or a placebo.
Identify the independent variable & Dependent variable
(medication vs. placebo) is the independent variable, while changes in participants’ anxiety levels form the dependent variable.
