Of 10 test scores, 5 are less than or equal to 83. What is the percentile rank of a test score of 83?
5/10 = 50%
Of 20 test scores, two are less than or equal to 83. What is the percentile rank of a test score of 83?
To determine the percentile rank of a test score of 83, you need to compare it to the other test scores and see how it ranks in relation to them.
First, identify the total number of scores, which is 10 in this case, so n = 10.
Next, count the number of scores that are less than or equal to 83. According to the information given, there are 5 scores that satisfy this condition.
The percentile rank is calculated by dividing the number of scores less than or equal to the given score by the total number of scores, and then multiplying by 100.
In this case, the calculation would be: (5/10) * 100 = 50.
Therefore, the percentile rank of a test score of 83 would be 50.
