33
Q

Name the different types of sampling

A

-Systematic
-Stratified

34
Q

What is opportunity sampling

A

People who are the most willing and available at the time

35
Q

What is volunteer sampling

A

Participants select themselves for the study

36
Q

What is random sampling

A

Every person in target population has an equal chance of being selected e.g pulling names out of a hat

37
Q

What is systematic sampling

A

Participants are selected using a set of patterns e.g for every nth person from a list

38
Q

What is stratified sampling

A

Participants selected according to their demographic group in relation to frequency in the target population then by using a random sample

39
Q

Evaluate opportunity sampling

A

-Quick
-Biased

40
Q

Evaluate volunteer sampling

A

-Participants are willing to engage
-Likely to have volunteer bias

41
Q

Evaluate random sampling

A

-Does not run the risk of investigator effects
-May not be representative of the whole population

42
Q

Evaluate systematic sampling

A

-Unbiased selection method so not investigator effects
-Time and effort consuming

Q

Evaluate stratified sampling

A

-Representative
-Time consuming
-Cannot fully represent every demographic

44
Q

Name four ethical issues

A

-Deception
-Protection from harm
-Privacy/Confidentiality

45
Q

A

-No manipulation of IV’s and DV’s so cant demonstrate cause and effect

62
Q

What is the mean

A

Arithmetic average, add up all the scores and divide by the total number of scores

63
Q

What is the median

A

-Middle value
-Place scores in ascending order and select middle value
-If there are two middle values, the mean is calculated

64
Q

A

Most frequent or common value

65

70
Q

73
Q

What is a table

A

Raw scores displayed in columns and rows; a summary paragraph beneath the table explains the results

74
Q

What is a bar chart

A

Categories usually placed along the x axis and frequency on the y axis. Height of column represents frequency for that item

75
Q

What is a histogram

A

Bar touch each other - data is continuous rather than discrete. There is a true zero

76
Q

What is a line graph

A

Frequency on one axis, data on the other axis is continuous. The line often shows how something changes over time

77
Q

What is a scattergram

A

Used for correlational analysis. Each dot represents one pair of related data. The data on both axis must be continuous
