Statistics - Levels of measurements

HideShow resource information
What is the definition of nominal data?
data that can be grouped into categories
1 of 12
What is an advantage of nominal data?
easy/quick to collect and analyse and patterns can be identified
2 of 12
What is the disadvantage of nominal data?
Lacks detail and information about each individiual pp. compared to interval and ratio data
3 of 12
What is ordinal data?
data that can change but can be ranked in an acceding order eg; scales such as 1-10
4 of 12
What is an advantage of ordinal data?
still easy to collect and understand but means you can meaningfully compare the scores against eachother
5 of 12
What is a disadvantage of ordinal data?
still lacks detail as the distance between pp scores is not revealed as it would be in interval or ratio data
6 of 12
What is interval data?
data that has fixed units of measurement, where no real/true zero exsists
7 of 12
What is an advantage of interval data?
very detailed as pps cannot just be ranked but the distance between each pp is also known as comparison
8 of 12
What is a disadvantage of interval data?
more consuming to collect than nominal or ordinal data as you need precise information about each pp, rather than just their rank order
9 of 12
What is the definition of ratio data?
the same as interval data but it has a meaningful zero point
10 of 12
What is an advantage of ratio data?
very detailed as pps cannot just be ranked but the distance between each pp is also known for comparison
11 of 12
What is a disadvantage of ratio data?
more time consuming to collect than nominal or ordinal data as you need precise information about each pp, rather than just their rank order
