Define social desirability bias.
Trying to present oneself in the best light by determining what the test is asking and responding in a way most acceptable to others.
29
Define filler questions.
Items added into a questionnaire or interview to disguise the aim of the study so that participants are less likely to alter their responses.

45
What is a hypothesis?
A testable statement predicting the difference between levels of the IV or a relationship between variables.
46
Define the null hypothesis.
A statement saying that there will be no difference in variables and that any difference is due to chance.
