Flashcards in Research Methods- Analysing&interpreting Data✅ Deck (24):

1

## Types of data

###
Quantitative

Qualitative

Primary

Secondary

2

## Qualitative data definition, advantages and disadvantages

###
Focuses on words

+) more detailed information

-) more difficult for analyse

3

## Quantitative data definition, advantages and disadvantages

###
Focuses on words

+) easier to analyse

-) not as rich, and meaningful

4

## Primary data

###
Data that is collected by the

Researcher themselves

5

## Secondary data

### Using someone else's findings

6

## Histograms

###
Bars joined together

Bars have to be equal width

Used for continuous data

No intervals are missed

All categories can be represented

7

## Bar charts

###
Bars aren't joined together

Used when comparing groups of data (not continuous)

Can be used to represent single statistics

Multiple data sets can be shown and compared

8

## Scattergrams

###
To show correlation/relationship

Line of best fit indicates relationship

Used to show type and strength of correlation

9

## Measures of central tendency

### Mean median and mode

10

## One way of calculating the measure of dispersion within a data set

### Calculating the range

11

## Range

### Subtracting the lowest score from the highest

12

## Standard deviation

### The measure of the spread of scores around the mean

13

## What three thing must you do in the sign test

###
Be looking for a difference

Have used repeated measures experimental design

Have data that is organised into categories

14

## The accepted level of probability is

### 0.05 meaning that the researcher will accept the hypothesis

15

## Your calculated critical value needs to be

### Equal to or less than the table value to be deemed as significant

16

## If the result is significant it means

### It matches your hypothesis and is effective

17

## Step one of the sign test

### Covert your data to nominal data- do this by allocating your data one of the following signs +,-,=

18

## Step 2 of the sign test

###
Total up the +'s

Total up the -'s

Disregard the ='s and adjust the number of participants according to the number of equals

19

## Step 3 of the sign test

### Identify the number of the less frequent sign, this is the S value

20

## Step 4 of the sign test

### Compare your S value against the critical value table. To do this you need to know if the hypothesis is one tailed or two tailed and the number of participants (N). You must also remember the accepted level of probability 0.05

21

## Peer review

### When psychological work is assessed by specialists in the same field to ensure any research intended for publication is or high quality

22

## What does peer review involve

### The written part of an investigation is scrutinised by a small group (normally 2 or 3) of experts. These experts should be unknown to the researcher and should be objective

23

## Aims of peer review

###
To allocate funding

To validate quality and relevance

To suggest improvements or amendments
