Q

What are the 4 scales of measurement?

A

1) Nominal (category membership)

2) Ordinal (ranked or ordered)

3) Interval (equal increments, but no real 0 point)

4) Ratio (real 0 point)

Q

What is Nominal as a scale of measurement?

A
  • The lowest level of measurement
  • Category membership (mutually exclusive categories)
  • Numbers assigned serve as
    labels but do not indicate
    numerical relationship

e.g. gender, political party,
religion

Q

What is Ordinal as a scale of measurement?

A
  • 2nd lowest level of measurement
  • Data can be ranked along a continuum
  • Intervals between ranks are not equal

e.g. race positions, attractiveness

Q

A Likert scale is used to measure agreement and disagreement on controversial topics. The scale goes from Strongly Agree, Agree, Somewhat Agree, Undecided, Somewhat Disagree, Disagree, Strongly disagree. The differences between Strongly Agree and Agree is not necessarily the same as the differences between Agree and Somewhat Agree.

Q

What is Interval as a scale of measurement?

A
  • 2nd highest level of measurement
  • Intervals between successive values are equal but no ‘true’ zero point

e.g. temperature, shoe size

Q

What are experimental methods?

A

A research design which allows us to make causal inferences about the influence of one or more variables on a variable of interest

20
Q

How do you conduct Experimental Methods?

A

By manipulating one or more variables and measuring the effect on other variables

e.g. Effects of alcohol on memory function

Manipulated variable = Amount of alcohol consumed

Measured variable: Score on the memory test

21
Q

What variables are manipulated?

a) Independent
b) Dependent
c) Control

A

a) Independent

22
Q

a) Independent
b) Dependent
c) Control

A

b) Dependent

23
Q

What variables are kept constant?

a) Independent
b) Dependent
c) Control

A

c) Control

24
Q

What are independent variables?

A

The variable that is manipulated and is hypothesised to bring about a change in the variable of interest

e.g. Treatment group

Group 1 = 2 Levels (drug and no drug)

Group 2 = 4 Levels (drug, counselling, mentoring and group therapy)

25
Q

What are dependent variables?

A
  • The variable that is measured
  • We compare differences in the DV under
    the different levels of the IV

e.g. exam score

26
Q

A group of students sit a multiple choice exam and receive a mark out of 80. We consider scores on this exam to be a variable that measures knowledge. What is the highest level of measurement we can consider this to be?

a.	Nominal

b.	Ordinal

c.	Interval

d.	Ratio
A

27
Q

Q

Doron is doing a study about stereotyping. He wants to know if the clothes that a lecturer wears influences student perceptions of teaching quality. Doron splits the students into two groups and gives his lecture to group 1 wearing a tracksuit and group 2 in a suit. He then asks students to complete a questionnaire about teaching quality.

The group variable (group 1 or group 2), is an example of what kind of data?

a.	Nominal

b.	Ordinal

c.	Interval

d.	Ratio
A
