Question

Skewness in a frequency distribution can be determined by comparing:

the median to the mean

or

the mode to the median

or

the mean to the mode

or

any two of the three measures of central tendency

Answer #1

Hello Sir/ Mam

**THE CORRECT
ANSWER IS any two of the three measures of central
tendency**

In the below picture, look at the positions of Mean, Median and Mode.

It is hence, clearly visible that all these 3 central tendencies follows a sequence and hence, skewness can be derived from any of these 2.

I hope this solves your doubt.

Do give a thumbs up if you find this helpful.

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

For each variable, any measures of central tendency (e.g., mean,
median and mode) that can be calculated should be noted.
Are the following correct:
Calories-scale/ratio-mean, median, and mode
Exercise-nominal-mode
TV- scale/ratio-mean, median, and mode
Fruits- scale/ratio-mean, median, and mode
Insurance-nominal- mode
Diabetes-nominal—mode
Age-scale/interval/ratio-mean, median, and
mode
Education level-ordinal- median and mode
Yearly salary-scale/ratio-mean, median, and
mode
Sleep-scale/ratio-mean, median, and mode
Alcohol-scale/ratio-mean, median, and mode

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...

Explain the differences among the mean, median, and mode. Give
an example in which the researcher might be interested in each of
these measures of central tendency.

What are measures of central tendency? What do they tell us? Do
mean, median, and mode fall in the same order? Be able to
calculate/identify each.

In a frequency distribution, the coefficient of
skewness based on quartiles is 0.5, if the sum of the upper and
lower quartile is 28 and the median is 11, find the value of lower
and upper quartiles.

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,...

The central tendency score that splits the distribution into two
equal sized groups:
a. median
b. mean
c. mode
d. standard deviation
e. variance
Dr. Dramatic wants to show participants three different videos
while recording their skin conductance. How many possible video
orders can be counterbalanced?
Identify the primary methodological difference (i.e.,
what the researcher does) between an experiment and a correlational
study.

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.

The value of one score in a distribution is changed from X = 20
to X = 30. Which measure(s) of central tendency is (are) certain to
be changed?
