Research Methods

This research method is a descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles

• Case Study
• Survey
• Observational
• Correlational
• Experiments

This research method is a technique for ascertaining the self – reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of the group.

• Survey
• Observational
• Correlational
• Experiments
• Case Study

This is a method of research where an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (the dependent variable).

• Experiments
• Case Study
• Survey
• Observational
• Correlational

What is a hypothesis?

• an educated guess

• an absolute solution

• a random guess

• an experiment

What is replication?

• cloning the scientist who first did an experiment

• doing an experiment for the first time

• doing an experiment again and getting different results

• Doing an experiment again and getting the same results

What is a sample in research?

• the whole target population

• a piece of food you get to try

• an educated guess

• only part of the target population

How can participant bias affect the outcome of a study?

• It can make others want to volunteer for the study

• It can invalidate it, if the volunteers hold bias that is counter to the opinions of those who are not part of the study, but are represented by it

• It can split the results in two

• It can prove it correct, because volunteer opinions accurately represent everyone in the population

The variable measured in an experiment is:

• The independent variable
• A null hypothesis
• The dependent variable
• An alternative hypothesis

In an experiment, the _________________ variable is tested by the researcher to observe its effect(s) on the _________________ variable.

• A.independent; dependent

• B.first; second

• C.dependent; independent

• D.research; results

Measure of central tendency calculated by adding up all scores and dividing by the number of scores in the data set.
