cause and effect

The reason something happens and the result of it happening.

why is it important that the individuals participating in the study are randomly assigned to either group that receives the supplement or to the group that receives the placebo?

This increases the likelihood that the two groups are the same so that any differences between the two groups are due to manipulation

When conducting survey research, what must a researcher do to generalize the results to the population?

Use random sample to select participants

operational definition

a description of something in terms of the operations (procedures, actions, or processes) by which it could be observed and measured. For example, the operational definition of anxiety could be in terms of a test score, withdrawal from a situation, or activation of the sympathetic nervous system.

devoted to uncovering basic structures that make up mind and thought

if the difference between the means of two groups is statistically significant, what does that mean?

difference between the groups is not likely due to chance

In order to control for Experimenter bias, researcher will often use

double-blind procedure

experimental research vs correlational research

experimental: you manipulate an independent variable and measure its effect on a dependent variable. Other variables are controlled so they can't impact the results. Correlation: you measure variables without manipulating any of them. You can test whether your variables change together, but you can't be sure that one variable caused a change in another.

Which of the following is the only method that allows a researcher to establish a cause-and-effect relationship?

experimentation

Researchers believe that an over-the-counter supplement may be useful in reducing memory impairment in older adults. they randomly assigned 40 adults between the ages of 50-90 years who had mild memory impairments to receive either a placebo or 90 milg of the supplement twice daily 18 months. At 6 month intervals, researchers conduct various memory tests. what type of research is used to study the impact of supplements on memory ability?
