Correlations

Question 1

Correlations

Answer 1

Show a link or relationship between two variables

Known as co variable 1 and co variable 2

No IV or Dv thus no manipulation of variables by researcher

Question 2

What does one point on a scattergram represent ?

Answer 2

Represents 2 scores from 1 ppt

Question 3

Correlation coefficient

Answer 3

Results from a correlation statistical test tell us how strong or weak a correlation is

Range for -1 to +1

Closer to 0 weaker the relationship

Question 4

What word do you not use for a correlation hypothesis?

Answer 4

Difference

Question 5

Non directional hypothesis correlation

Answer 5

There will be a significant relationship between (operationalised co variable 1) and (operationalised co variable 2)

Question 6

Directional hypothesis correlations

Answer 6

There will be a significant positive or negative relationship between (operationalised co variable 1) and (operationalised co variable 2)

Question 7

What is the difference between a correlation and an experiment ?

Answer 7

Experiment has 2 condition

Correlation has 2 variables

Question 8

Experiment

Answer 8

Experiment the researches is looking for a difference between conditions

Researcher manipulates IV and measures effect on DV

Possible to establish cause and effect

Question 9

Correlation

Answer 9

Correlation shows relationship between co variables

No manipulation by researcher

Cause and effect cannot be established

Question 10

Correlation Ao3 strength

Answer 10

No manipulation of variables so it’s appropriate to use when studying sensitive issues that may raise ethical issues

Or when it may be inappropriate to manipulate a situation

Whereas in an experiment it would be impractical to investigate a cause and effect

Question 11

Correlation Ao3 (L)

Answer 11

Difficult to establish cause and effect between 2 variables as only a relationship is found

Thus other extraneous variables could be responsible for the relationship found

Lowering internal validity
