variables

Question 1

define an aim

Answer 1

general statement of what the research intends to investigate

(e.g an investigation of how colour affects the recall of words)

Question 2

define hypothesis

Answer 2

clear, precise, testable statement that states the relationship between the variables being investigated
(e.g words will take longer to recall if they are presented in a different colour to the meaning of the word)

Question 3

define variable

Answer 3

factor that can change in an investigation

Question 4

define independent variable

Answer 4

an aspect of the experimental situation that the researcher manipulates or changes naturally
(e.g the colour of words)

Question 5

define dependent variable

Answer 5

measured by the researcher to see how it changed
(e.g time taken to read a word)

Question 6

define operationalisation

Answer 6

turning abstract concepts from your aim (e.g intelligence) into clearly defined variables that can be measured (e.g IQ)

Question 7

define a directional hypothesis

Answer 7

states the kind of difference or relationship between the IV and DV

1 TAILED HYPOTHESIS

Question 8

define a non directional hypothesis

Answer 8

predicts that there will be a difference between conditions (but doesn’t predict which direction it will go)
