What are the 4 levels of data?
Nominal, Ordinal, Interval, Ration (NOIR)
1 of 17
What is nominal data ?
Data which has been collected in catagories using tallies (ie. Coding schemes)
2 of 17
What is ordinal data?
Data which records the order of participants scores eg. 1st, 2nd, 3rd OR data collected from unoffical scales
3 of 17
What is interval data?
Data collected from offical scales, can contain negatives eg.Temperature
4 of 17
What is ratio data?
Data collected by countig scores per person OR data collected from offical scales, can only contain positive numbers eg.height
5 of 17
Mode, Median and mean are all measures of ....
central tendency
6 of 17
Which average is used for nominal data?
Mode
7 of 17
which average is used for ordinal data?
Median
8 of 17
Which average is used for interval/ratio data?
mean
9 of 17
If outliers are present which average should be used?
median
10 of 17
what is meant by measures of dispersion?
The range
11 of 17
What type of graph should be used for experiments?
Bar chart (plotting the average result)
12 of 17
what type of graph should be used for correlations?
Scatter graph
13 of 17
Fill in the gaps: Ratio/interval data can be converted into _______ data by ______ ____ ______ ______ _______
ordinal, by putting the results into order
14 of 17
A test of difference =
Independant measures and repeated measures
15 of 17
A test of realtionship =
Association/Correlation
16 of 17
What does this statement mean?: The research was found to be significant at the level of significance P<0.05
The probability that the results are due to chance or extraneous variables is less than 5%
