Question

Edit question You are given two identical sets of data A and B with the largest value from the data set B being three times greater than the largest value of data set A.

Explain clearly How do the standard deviations of the two data sets compare?

Answer #1

You are given two identical sets of data A and B with the
largest value from the data set B being three times greater than
the largest value of data set A. Explain clearly How do the
box-and-whisker plots of the two data sets compare?

Consider two data sets, A and B. The sets are identical except
that the high value of data set A is three times greater than the
high value of data set B.
(a) How do the medians of the two data sets compare?
It is impossible to know how the medians compare.
Both sets have the same median.
Set A has a higher median.
Set B has a higher median.
(b) How do the means of the two data sets...

Comparing two data sets, you state in a memo to your supervisor
that data set B has a comparatively larger spread or variance.
Data set A: mean = 42.5, std deviation = 68.0, coefficient of
variation = 1.6
Data set B: mean = 28.9, std deviation = 60.7, coefficient of
variation = 2.1
Your incredulous supervisor says that you must be wrong since
data set A clearly has a higher standard deviation. Provide an
argument supporting your contention...

Given two sets A and B, the
intersection of these sets, denoted A ∩
B, is the set containing the elements that are in both
A and B. That is, A ∩ B =
{x : x ∈ A and x ∈
B}.
Two sets A and B are
disjoint if they have no elements in common. That
is, if A ∩ B = ∅.
Given two sets A and B, the union of
these sets, denoted A ∪ B,...

Compare the three data sets on the right.

A dot plot has a horizontal axis labeled from 4 to 10 in increments
of 1. The graph consists of a series of plotted points from left to
right. The coordinates of the plotted points are as follows, where
the label is listed first and the number of dots is listed second:
5, 1; 6, 4; 7, 5; 8, 4; 9, 1.

Step 1
Create a bar graph that examines a variable or variables in
your data set.
Step 2
Find the sample mean, median (if it exists) mode for each set
of data
Next find the sample standard deviations for each set of
data
Create a box and whisker plot for each variable for each set

Eliminate any outliers from the samples. Redo part 1 for each
variable (if necessary, if not...

If you are using a bar graph or histogram to compare two sets of
data, explain why it is best to use relative frequencies.
