Please answer all question
Question 1
A satisfaction survey asks you to rank a service in one of five classes from "not at all satisfied" to "extremely satisfied". This level of measurement is best described as:
a-interval data
b-ordinal data
c-nominal data
d-discrete data

Question 2
A table summarizing a set of data by category expressed as a percentage is:
a-histogram
b-relative frequency table
c-ogive
d-grouped frequency table

Question 3
The best representation comparing both totals and subcategory values in a single chart is a:
a-component bar chart
b-histogram
c-simple bar chart
d-pie chart

Question 4
A frequency polygon having a peak offset to one side is:
a-... impossible!
b-kurtosis
c-symmetric
d-skewed

Question 5
Which of the following is an incorrect statement?
a-The frequency of each category is represented in histograms by the area of each bar, not the height.
b-Histograms summarize and display nominal data.
c-Histograms always have no space between bars.
d-A frequency polygon is constructed from a histogram.

Question 6
Calculate the mean of the following data.

7, 4, 9, 4, 2, 5, 0, 3

Question 7
In the following histogram, which measure of location would be preferred as a middle value?

a-mode
b-mean
c-1st quartile
d-median

Question 8

Comparing spreads to two datasets when means are substantially different is conducted using:

a-an interquartile range

b-standard deviation

c-coefficient of variation

d-variance

Question 9
A distribution's second quartile, Q2, is equal to its:
a-mean
b-stem
c-median
d-coefficient of variation

Question 10
The square root of the variance is called the:
a-interquartile range
b-coefficient of variation

ogivec-

d- standard deviation

Explanation / Answer

These are too many questions. As per Chegg rules, there can be just one question per post. But I will still answer first 4 questions and hope for an upvote.

1. Answer is ordinal data.

Ordinal data is a categorical, statistical data type where the variables have natural, ordered categories and the distances between the categories is not known.

Nominal data is just names, with no order or comparable value.

Discrete data are that can be categorized while continous/range/interval data are restricted to separate values.

But since best description is asked so it would be ordinal data.

2.

A table summarizing a set of data by category expressed as a percentage is:

Answer is a-histogram.
a-histogram
b-relative frequency table
c-ogive
d-grouped frequency table

3.

The best representation comparing both totals and subcategory values in a single chart is a:
a-component bar chart
b-histogram
c-simple bar chart
d-pie chart

Component bar chart is the answer.

In this the total values, divided into sub-categories are shown for each of the category.

Which allows to see both total values of the categories and the subcategories division in the respective categories

4.

A frequency polygon having a peak offset to one side is:
a-... impossible!
b-kurtosis
c-symmetric
d-skewed

It is called skewed. It means the peak is deviated/shifted/ leaned from its normal distribution natural position in center.

so answer is d.
