LEVELS OF DATA

There are 3 types of data -

1. NOMINAL

2.ORDINAL

3.INTERVAL

NOMINAL

"this is a measure of how many things occur within a category"

eg when measuring what kind of toy children have in their room, we would count how many board games, card games, cars ect to give us categorised data.

This type of data gives us the least amount of information as we don't know anything about the type of board game for instance, just how many of a category there is.

Often used when conducting observations as categories of behaviour are set out at the start of an observation.

ORDINAL

"Measure of each item or person in the data set"

e.g. organising a group of people into height order from tall to short .....

...this would allow an understanding on where each people falls in relation to others in the data set

INTERVAL

"Giving individual values for each participant"

• Gives the most information
• Tended to be gathered when conducting experiment
