2020 Year 11 Psychology - readiness task

The following are 2 steps of the 7 step process

• Formulate a hypothsis & Identify IVs and DVs

• Report Findings & Design a research method

• Collect and analyse the data & complete research

• Report Findings & Design an informed consent

A variable is:

• a factor that can change the IV only

• a factor that can change the DV only

• any factor that can change

• a factor that will not change

What is the difference between a research question and an aim?

• A aim is more specific than a research question and outlines what the research wants to find out

• A research question is more specific than an aim and outlines what the research wants to find out

• An aim can also be a question.

• There is no difference

A hypothesis is:

• a prediction about the results of an experiment

• a testable prediction of the outcome of the experiment

• an idea of the outcome of the experiment

• a testable prediction about the relationship of 2 or more factors

The purpose of an experimental group in research is to:

• ascertain the effects of the dependent variable

• eliminate the effect of the dependent variable

• ascertain the effects of the independent variable

• eliminate the effects of the independent variable

The best definition of a random sample is:

• a group of participants selected by picking names at random from the phone book

• a group of participants selected from the population by putting all the names in a hat and drawing them out at random

• a group of participants selected from the population in such a way that each member of the population has an equal chance of selection

• a group of participants selected from the population by means of a random number generator on a computer

An Independent Variable

• is only allocated to the control group

• is a second unwanted variable

• is the variable that is measured by the researcher

• is the variable that is manipulated by the experimenter

An extraneous variable is

• a variable other than the IV that has a systematic effect on the DV

• a variable that can effect the IV and DV

• any unwanted variable (other than the IV) that might change the DV

• any unwanted variable (other than the IV) that will affect the results of the study.

The three experimental designs are:

• Random allocation, Matched Participants & Independent Groups

• Repeated Measures, Matched Participants & Independent Groups

• Matched Participants, Repeated Measures & Order Effects

• Stratified allocation, Independent Groups & Independent Groups

What type of research design involves testing different age groups only once?

• longitudinal

• cross-sectional

• sequential

• matched-pairs
