Q

What are three weaknesses of Longitudinal?

A

Ppts may atrophy

Costly as its over a long period of time

Very time consuming

18
Q

What are two weaknesses of cross-sectional studies?

A

You cant measure change in behaviour

Lots of extraneous variables may occur due to wide sample

19
Q

What are two weaknesses of self-report techniques?

A

Results may suffer from social desirability bias as they want to please the researcher

Inter-rater reliability may be low as all participants may record data differently

20
Q

What are two weaknessess of online research?

A

Very hard to properly debrief ppts who partake in anything such as questionnaires online

Issues with terms and conditions may lead to complicated issues with gathering data for study

21
Q

What are two weaknesses of random sampling?

A

very time consuming as you need to contact people from a potentially long list

it cant be done with access to the sample frame

22
Q

What are two weaknesses of systematic sampling?

A

it is time consuming

it is not truly unbiased unless we select the Nth number with a random technique

23
Q

What are two weaknesses of opportunity sampling?

A

normally leads to an unrepresentative sample

could lead to sample displaying specific participant variables (e.g. volunteer bias)

24
Q

What are two weaknesses of Stratified sampling?

A

it is very time consuming

it is potentially impossible due to cases of rare characteristics

25
Q

What are three weaknesses of Quota sampling?

A

it is very time consuming

it is potentially impossible in some cases (e.g. hard to access people)

it is bias due to ppts being selected by researcher

26
Q

What are two weaknesses of self-selected sampling?

A

volunteer bias may be shown in the sample

ppts may display unhelpful ppts variables such as demand characteristics due to the volunteer nature of the sampling method

27
Q

What are two weaknesses of Snowball sampling?

A

The sample may be unrepresentative of society on the whole

Data can’t be generalised due to niche groups

28
Q

What are two weaknesses of Independent groups?

A

It requires double the sample size due to ppts taking part in separate conditions

you can’t account for ppt variables

29
Q

What are two weaknesses of Repeated measures?

A

Order effects may occur

Participants have a greater likelihood to alter their behaviour due to guessing the aim of a study

30
Q

What are two weaknesses of Matched pairs?

A

it is time consuming and potentially expensive to match ppts on key variables

it may be impossible in cases of uncommon characteristics

31
Q

What are two weaknesses of a bar chart?

A

They require extra explanation

It doesn’t show interdependency or causation of data

32
Q

What are two weaknesses of Pie charts?

A

They can easily become complex

They dont reveal key assumptions or causes of the data

33
Q

What are two weaknesses of line graphs?

A

They easily become messy + complicated

Limited to numerical data only

34
Q

What are two weaknesses of scatter graphs?

A

they can be hard to read

they only allow two variables to be analysed

35
Q

What are two weaknesses of a histogram?

A

you cant use it to compare sets of data

the use of intervals prevents the calculation of an exact measure

36
Q

What are two weaknesses of a Mean?

A

they are effected by outliers

you cannot use the mean for nominal data

37
Q

What are two weaknesses of a median?

A

you cant calculate the median for nominal data

doesn’t take into account all values in the data

38
Q

What are two weaknesses of a mode?

A

not always helpful for a study

it ignores all other parts of the data

39
Q

What are two weaknesses of Standard deviation?

A

it can be influenced by outliers

can be incredibly complex to calculate

40
Q

What are two weaknesses of the range?

A

It is heavily influenced by the presence of outliers

it ignores all other data in the set bar two values
