Levels Of Measurement

Question 1

Nominal data

Answer 1

Simply counting the amount of times a bhvr occurs. Most basic level of measurement which usually uses a tally chart.

Question 2

Ordinal data

Answer 2

Data is ordered from highest to lowest (or vice versa) or ordered on subjective info such as a rating scale

Question 3

Interval data

Answer 3

Data is placed on a fixed precise scale, with equal measurement between each point. Zero does not mean nothing it is simply another number of the scale (temp)

Question 4

Ratio data

Answer 4

Data is placed on a fixed precise scale, with equal measurement between each point. There is a true zero that data cannot go below (height, shoe size, weight)

Question 5

Nominal strength

Answer 5

It is simple to collect and easy to analyse so this method is a lot less time consuming than other levels of measurement

Question 6

Nominal weakness

Answer 6

Gaps between variables are non-mathematical. There is no measurable gap between yes and no. Therefore the results received are extremely and not very scientific

Question 7

Ordinal strength

Answer 7

Provides more detail than nominal level data which may allow a mor

Question 8

Ordinal weakness

Answer 8

Unequal distances between units of measurements

Question 9

Interval strength

Answer 9

Equal differences in characteristics are are represented by equal differences in the measurements

Question 10

Interval weakness

Answer 10

There is no true zero point ratios cannot be established e.g. It would not be appropriate to say 60 degrees is twice as hot as 30 degrees

Question 11

Ratio strength

Answer 11

There is a meaningful zero point which allows for the interpretation of ratio comparisons. Time is an example of a ratio measurement scale. Not only can we say the difference between three hours and five hours is the same as the difference between eight hours and ten hours (equal intervals) but we can also say ten hours is twice as long as five hours (a ratio comparison)
