Part A

State whether the data values are quantitative or qualitative.

What is the level of measurement?

Part B: Organize Data into a frequency distribution

• If The values are qualitative use a frequency distribution including a column for percentage or Angle.
• If Data are quantitative Organize the data into a number of classes of your choice (5 minimum 8 maximum)

Part C : Graph

• Present the data using at least two statistical graph of your choice. ( what two graphs should I be using?)

Answer 1

SolutionA:

data values are quantitative since we have measured.

the level of measurement is interval

SolutionB:

Part B: Organize Data into a frequency distribution

Data are quantitative Organize the data into a number of classe

Class Interval	Frequency
1-20	10
20-39	8
39-58	2
58-77	5
77-96	5

Solutionc:

Its quantitative data

plot

histogram and boxplot

steps:

paste the data in excel

select the data and go to insert>histogram

From histogram we observe that distribution is positively skewed

From Boxplot we get 5 number summary as

minimum=1

Q1=13.5

Q2=30

Q3=69.25

maximum=96
