The control group's score of 47.26 on the pretest put it at the 26th percentile. Does this percentile score represent nominal, ordinal, or interval scale data?
Answers
Answer:
Ordinal scale data
Step-by-step explanation:
“Ordinal” means “ordered”. When someone is to be ranked according to the position they are in a set of data, it comes under ordinal scale data.
Percentile:
A percentile is nothing but the position of data which is better or higher in quality. For example, if a person gets a score of 99 percentile, that means the person is better than 99 members out of 100 members. So, it literally means that he is in the top position or is better than anyone in the set.
Ordinal scale data means the numbers are rank ordered from worst to best (or vice-versa) in a set of data.
From the question, the given data is that;
The control group’s score is 47.26
The group is at the 26th percentile.
This means that in the 100% of the data set, the control group is better than 26% of the groups.
Here, the control group's position is set according to an order.
So, according to the given data, the percentile score of the control group is an ordinal scale data.
