Percentile for Grouped Data

The formula that is used in finding Percentile for Grouped Data is (the picture shown) where LB is:

• A. The total frequency

• B. The lower-class boundary of Pk class

• C. The width of the class interval

• D. The percentile of the Data

What is the first step to calculate the percentile rank, when you need to know the percentiles of the item you're ranking?

• A. Divide the number of values below by the total number of values

• B. Put your data in ascending order

• C. Using the formula, calculate the quotient between the number of values below your score and the number of all the values in your data set.

• D. D. Multiply the result by 100 to get a percentage. With the previous test score example, calculate percentile.

The 10 students obtained scores of 38, 47, 49, 58, 60, 65, 70, 79, 80, and 92 in the exam. Using the percentile formula, calculate the percentile of the score 70.

• A. 85

• B. 60

• C. 70

• D. 55

• A. Percentile

• B. Decile

• C. Quartile

• D. Median

_____ are raw data, meaning they have just been collected but not sorted into any group or classes

• A. Grouped Data

• B. Ungrouped Data

• C. Frequency Table

• D. Percentile

It is the term for the lower class boundary of Pk

• A. LB

• B. Pk

• C. N

• D. i

It is the term used for the total frequency of a data set

• A. f

• B. N

• C. i

• D. Pk

It is a measure of the relative standing of observation within a data and is used to characterize values accordingly

• A. Percentile Data

• B. Percentile Formula

• C. Percentile for Ungrouped Data

• D. Percentile for Grouped Data

After you arrange them, how are you going to get the percentage of the data?

• A. Multiply the result by 100 to get the percentage

• B. Divide the number of values below by the total number of values

• C. By Subtracting it to 100

• D. By Adding it to 100

After dividing the total number of values, using the formula, how are you going to get the percentage?

• A. Multiply the result by 100 to get the percentage

• B. Put your data in ascending order

• C. Divide the number of values below by the total number of values

• D. Calculate the quotient between the number of values below your score and the number of all the values in your data set.
