Unit 1 Part 2 SM

Which scatterplot shows the strongest negative relationship between the variables?

• 
• 
• 
• 
• 

Independent Variables are

• Never controlled

• Manipulated by the researcher

• Constantly changing

• Notes from experiments

A Correlational study

• Has all controlled variables

• Measures relationships and no variables controlled by researcher.

• Has one controlled variable

• Can not show Cause or Effect

In a study, injections of saline solution (which contains no chemicals) were shown to be quite effective for relieving pain. this is an example of:

• the experimenter effect

• a placebo effect

• the experimental effect

• an order effect

The experimental group is:

• Study in which neither the experimenter nor the subjects know if the subjects are in the experimental or control group

• study in which the subject do not know if they are in the experimental group or control group

• subjects in an experiment who are not subjected to the independent variable and may receive a placebo treatment

• the group to which the researchers manipulate the independent variable

The main purpose of ethical guidelines for research in Psychology is to:

• minimise the problems that participants cause for researchers

• guarantee that the experimentation runs without problems

• protect the welfare and rights of the participants

• ensure that any results published will not be challenged

in an experiment, DEBRIEFING of participants most likely includes information such as:

• each participant's own results in the study

• the number of hours participants will be expected to participate

• the procedures that will be required fo participants during the experiment

• the individual results of the other participants in the study

what is the scientific method?

• a process of systematic observation, measurement and experiment to formulate and test hypotheses

• clear and detailed statement about how you will measure the data collected about the variables

• a sample that has characteristics that are similar to those in the population

• the group to which the researchers manipulate the IV

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

• first; second

• independent; dependent

• dependent; independent

• research; results

Method of intense study of just one individual:

• Naturalistic Observation

• Experimental Study

• Case Study

• Survey
