Question

For the following data regarding values/scores on a test:

a. What is the n for this data?

b. what is the range for this data?

c. what is the level of measurment?

d. which is more appropriate, a regular (simple) or grouped requency distribution table?

e. explain why you chose this type of table.

f. Construct the appropriate table and graph for this type of data, and include it in your responses.

g. Calculate the mean, median, and mode for this data.

22,37,14,17,27,41,30,13,19,21.49,37,29,20,16,17,34,16,35,24,16,12,29,30

Answer 1

a. What is the n for this data?

n=sample size=23

Solutionb:

b. what is the range for this data?

Range=max-min=41-12=29

c. what is the level of measurment?

level of measurement is interval

Solutiond:

, a regular (simple) which is histogram

Solutione:

Histogram used to plot the frequency of score occurrences in a continuous data that has been divided into classes called bins

Solutionf:

Histgram is

Solutiong:

mean=sum/total=556.49/23= 24.19522

median is middlemost value after data arranged in ascending order.

median=22

mode =16(frequency is 3)

mean>median

positively skwed distribution
