Question

5. In the GSS2012 dataset, using *Explore,* determine the
measures of central tendency and spread for HAPMAR (Happiness of
Marriage). Examine the statistics and determine which measures of
central tendency and spread are most appropriate.

Mean:
*1.37*

Median:
*1.00*

Standard deviation: *.540*

Range:
*2*

Interquartile Range: *1*

- Highlight the measure you would use as the measure of central tendency:

Mean Median Mode

- Why did you make this selection? Do not give me a definition of mean/median/mode, but rather an explanation as to why it is appropriate.
- Highlight the measure you would use as the measure of spread:

Standard deviation Range IQR

- Why did you make this selection Do not give me a definition, but rather an explanation as to why it is appropriate.?

Answer #1

The three commonly used measures of central tendency
are
mode, median, and mean.
percentage, midpoint, and mean.
mode, midpoint, and ratio.
median, rate, and mode.
T he purpose of univariate descriptive statistics is
to
summarize relationships between many variables.
display the essential meaning of variables measured at the
interval-ratio level.
combine nominal and discrete variables.
summarize a single variable.
The most appropriate measure of central tendency for
gender would be the
median.
mode.
mean.
None of the above
If you...

Mean, median, and mode are the three measures of central
tendency that we learned about in this class. We use these to
describe the center of a distribution. For each of the following
examples please identify which measure of central tendency should
be used given the situation.
A negatively skewed distribution
A platykurtic distribution

In statistics, there are several common measures of central
tendency of a distribution of values, including the arithmetic
mean, the median and the mode. Under what circumstances would it be
better to use the median instead of the arithmetic mean? And why
would the arithmetic mean be misleading? Please cite examples.

5.
What measure of central tendency (mean, median, or mode) should you
use if you wish the deviations above the measure to be equal in
size to the deviations below the measure?

Seeing if i did these right
What is the goal of central tendency?
The goal of central tendency is to
find the “middle” of a distribution. It identifies one single
measure that best describes a set of data
Find the mean, median, and mode for
the following sample of scores: 5, 4, 5, 2, 7, 1, 3, 5
Mean________4_______
Median_______4.5________ Mode_______5________
Find the mean, median, and mode for the following sample of
scores: 3, 5, 7,, 3, 9, 8, 3,...

choose the most appropriate measure of central
tendency (mean, median, mode) and dispersion(range, inter
quartiles, standard deviation) and whyd you choose them
a scientist is studying the effect of socioeconomic
class on the average family size. while reviewing the distribution
of the collected data, the scientist found that a large majority of
the families had two or less children while very few families had 5
or more children

1: Compute measures of central tendency below:
a)Mean, median, and mode for the grades taken by students
b)Mean, median, and mode for the number of hours studied
Discussion question 2: Does the number of hours studied correlate
with the grades taken? Please provide a narrative explaining the
relationship between the number of hours studied and the grades by
running correlation analysis in Excel.
In Excel, use insert function to compute the measures of
central tendency and use the CORREL function...

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)....

1. Why do we prefer the median as a better measure of central
tendency when the data are positively/negatively skewed? Are there
times in which mean or mode should be used instead? Explain your
answer.
2. Find an article about the misuse of statistics and share what
you have learned from the article. Then, find an example of when
statistics were misused/skewed and state the reason why you think
the statistics were reported that way.
