types of data

Question 1

What is a positive correlation ?

Answer 1

As one variable increases so does the other and as one decreases so does the other

Question 2

What is a negative correlation ?

Answer 2

As one variable increases the other decreases vice versa

Question 3

What is the weakness of quantitative data ?

Answer 3

Lower ecological validity because there is not enough data therefore can not generalise for real life scenarios

Question 4

What are the strengths of qualitative data ?

Answer 4

Allows participants to elaborate on their thoughts and feelings

It is rich In depth data

Question 5

What is a weakness of qualitative data?

Answer 5

Difficult to analysed because there is a range of answers meaning we can’t se overall trends

Question 6

What is primary data ?

Answer 6

Data that has been specifically collected for the purpose of the purpose of the investigation by the researcher

Question 7

What is the strength of primary data ?

Answer 7

It is authentic data obtained from the participant themselves for the purpose of a particular investigation

Question 8

What is secondary data ?

Answer 8

Data that has been collected by someone other than the person who is conducting the research.

data that already exists

Question 9

What is the strength of secondary data ?

Answer 9

Inexpensive and easily accessed requiring minimal effort if secondary data already exists then there’s no need to collect primary data

Question 10

what are the strengths of a metà analysis ?

Answer 10

Secondary data do it is less time consuming as experiments don’t need to be carried out

uses data from many different studies which means we can be much more confident about drawing conclusions from what they find

Question 11

When should a mean be used ?

Answer 11

When there are no extreme data scores
outliers

Question 12

When should a median be used ?

Answer 12

When should a median be used ?

Question 13

What is a strength of the mode.?

Answer 13

Shows the more common category in normal data

Question 14

What is a weakness of using the mode ?

Answer 14

Less sensetive than mean as only a couple values may be used

there is likely to be no mode or more than one

Question 15

how do we calculate the range ?

Answer 15

Biggest number in the data minus the smallest number in the data

then add 1

Question 16

What is a negative of using the range ?

Answer 16

Only takes into account the 2 most extreme values so isn’t representative of the whole data set

Question 17

What is standard deviation ?

Answer 17

How far scores deviate from the mean

Question 18

What is a strength of standard deviation ?

Answer 18

More precise as it uses all values

Question 19

What are double negative questions?

Answer 19

2 negatives which really just mean a positive

it creates unecesssry confusion there is a simpler way of asking and the researcher should be clear with their questions

Question 20

What are the strengths of quantitative data ?

Answer 20

Less Biased as numbers are objective so clear what the answer is therefore it is easier to analyse

Question 21

What is the weakness of secondary data ?

Answer 21

There may be substantial variation in the quality and accuracy of secondary data. Information might be out dated or incomplete

the content of the data may not match the researchers needs it objectives

Question 22

What is the weakness of primary data ?

Answer 22

Producing primary data is time consuming
