hypothesis, IV's and DV's

Question 1

correlation

Answer 1

relationship between 2 things without manipulating IV

Question 2

experiment

Answer 2

manipulate IV and see effect on DV

Question 3

Aim

Answer 3

a statement of what the researcher wants to find out in the study

Question 4

operationalisation

Answer 4

how to measure it

Question 5

what must be operationalised in an hypothesis

Answer 5

the IV and the DV

Question 6

alternative/expected hypothesis

Answer 6

the main hypothesis, predicts difference

Question 7

strengths of correlational techniques

Answer 7

-used when a lab experiment would be unethical as variables are not manipulated
-measure strength of relationship between variables

Question 8

null hypothesis

Answer 8

any effect occurs by chance and not bc of IV you’ve manipulsted

Question 9

limitations of correlational techniques

Answer 9

-not possible to establish cause and effect through conducting correlation
-only identify linear relationships

Question 10

independant

Answer 10

the variable the researcher manipulates

Question 11

dependant

Answer 11

the variable the researcher measures

Question 12

two types of experimental hypotheses

Answer 12

-directional and non directional

Question 13

directional hypothesis

Answer 13

-provides specific nature/direction of the difference between two or more variables, e.g higher ,lower, more,less

Question 14

non directional hypothesis

Answer 14

-predicts a difference will exist but without predicting exact direction of difference e.g. difference
