Flashcards in Data handling and analysis Deck (31):

1

## What are meta-analyses and what type of data does this collect?

### Collecting data from several studies with the same research aims and re-analysing them; Secondary data

2

## What is the mean?

### Average score

3

## What is primary data?

### Data collected first hand by the researcher, directly from their own participants. It is new data that has never been collected before

4

## What is the mode?

### The most frequently occurring data/number

5

## What is the median?

### The middle number

6

## What are the measures of dispersion?

### Range and standard deviation

7

## What should you display on a bar chart?

### Categorical/nominal data - set integer values, e.g. students in a class

8

## What should you display on a histogram?

### Continuous data - can take on any value, e.g. weight

9

## What should you display on a scatter graph?

### Correlational data

10

## What does a positive skew look like?

### Scores are mainly below the mean and so are concentrated to the left of the graph

11

## What does a negative skew look like?

### Scores are mainly above the mean and so are concentrated to the right of the graph

12

## Describe the range

### Biggest no - smallest no. The higher it is the more variability is in the data set

13

## Describe the standard deviation

### Tells you the spread of data around the mean and to see the relationships between scores

14

## What type of data uses the sign test?

### Nominal

15

## What are co-variables?

### The variables investigated in a correlational study. The relationship between them is investigated, not cause and effect

16

## What is nominal data?

### Frequency data - it measures how many; uses the sign test or chi-squared test

17

## What is ordinal data?

### Continuous data - data along a scale with inexact quantities between points; uses the Mann-Whitney or Wilcoxon tests

18

## What is interval data?

### Continuous data - data on a scale with exact and equal intervals between points; uses the t-test or Pearson's r

19

## What rhyme do you use to remember nominal data tests?

### Naughty children swear constantly

20

## What rhyme do you use to remember ordinal data sets?

### Only men want sausages

21

## What rhyme do you use to remember interval data sets?

### I usually rate pizza

22

## Which measure of central tendency is the most sensitive and what does this make it?

### Mean; makes it more representative of all values

23

## What is coding and when is it used?

### The means by which qualitative data is summarised into meaningful categories for analysis. Used in thematic analysis

24

## What is the difference between content and thematic analysis?

### Thematic analysis is different from content because you do not count the themes, you cluster them under headings

25

## How could thematic analysis be carried out on interview recordings?

### Use the recordings to make a transcription of the interview, use coding to analyse this and then review it looking for themes linked to violent crime that sum up the work

26

## What is content analysis?

### Summarising qualitative data into quantitative data through systematic examination of the material in order to determine meanings that underlie the content and counting the number of times a theme appears

27

## What is thematic analysis?

### A method of qualitative research linked to content analysis, which involves analysing data to identify the patterns within it and summarising key ideas under these subheadings (but not counting themes)

28

## What is secondary data?

### Secondhand data which already exists and have not acquired from participants

29

## What measurement of central tendency should be used with nominal data?

### Mode

30

## What measurement of central tendency should be used with ordinal data?

### Median
