There are decrpitive statistics based on 91 countires. Describle
and compare following two data sets (distribution/shape, central
tendecies, variability, potential outliers etc). In case of need
compute additional statistics.

Altering Data Sets: Consider the following data
set:
24, 31, 34, 36, 40, 44
Without calculating the statistics, describe what would happen
in each case.
(a) The 24 is replaced by a 12.
The mean would decrease.The median would stay the
same. The standard deviation would
increase.All of these are true.
(b) The 24 becomes a 22 and the 44 becomes a 46.
The median would increase.The standard deviation would
increase. The mean would increase.All of
these are true.
(c) The 36 becomes a 44.
The mean...

For my Healthcare Statistics class....Consider two different
data sets and then for each data set, propose your idea of what
graph would best represent the key information. For each, be sure
to include the type of graph along with what would be shown on each
axis. The key data in the first data set is a list of all the
injuries that a clinic saw in a month. The other data set has key
data on the number of minutes...

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...

1. Prepare a report on
the center and spread of
data.
- Begin by visiting www.edmunds.com (Links to an
external site.) and searching for a used car near you (or make one
up):
- In advance, decide what make, model, and year you
will search.
- Record the price of 20 of that particular vehicle
being offered.
2. Create a histogram of the prices.

Data Set A- 7,7,7,9,9,9,10
Data Set B- 4,6,6,6,8,9,9,9,10,10,10
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...

Topic: Summarizing Data and Describing Relationships Using
Technology
collect quantitative data from the Internet, StatCrunch, and
compute summary statistics of your data.
Do this assignment:
Collect 50 or more quantitative data.
a.) Using StatCrunch, compute the following five summary
statistics:
1. Sample mean
2. median sample
3. standard deviation
4. range
5. interquartile range (IQR).
b.) Then, construct a histogram. You do not have to construct a
histogram with sliders.
Make sure your data set is large enough (50 items)....
