the difference between central tendency & variability?

		A. There is no difference they mean the same thing
		B. central tendency describes the average score, while variability describes how the scores are spread out C. none of the above
		D. central tendency describes how the scores are spread out, while variability describes the average score

Expert Solution

Answer: B. central tendency describes the average score, while variability describes how the scores are spread out

Explanation:

The Measures of Central Tendency are the averages or the "statistical constants which enable us to comprehend in a· single effort the significance of the whole." They give.us an idea about the concentration of the values in the central part of the distribution.

They are: Mean, Median, Mode, Geometric Mean, Harmonic Mean

The measures of dispersion examines the scatteredness of the data values. We study dispersion to
have an idea about the homogeneity or heterogeneity of the distribution. It tells us the spread of the data values from their averages.

They are: Range, Quartile Deviation, Mean Deviation, Standard Deviation, Variance.

Discussion: Central Tendency and Variability Understanding descriptive statistics and their variability is a fundamental aspect of statistical analysis. On their own, descriptive statistics tell us how frequently an observation occurs, what is considered “average”, and how far data in our sample deviate from being “average.” With descriptive statistics, we are able to provide a summary of characteristics from both large and small datasets. In addition to the valuable information they provide on their own, measures of central tendency and variability...

Step 1 Find examples of measures of central tendency and variability. Find an example of data presented in some print medium–newspaper, magazine, journal, etc.–and focus on the measures of central tendency and measures of variability. Step 2 Write about your example. Prepare your discussion posting by answering the following: Which measures or central tendency and variability were presented in the article? Were they presented correctly? Is there a clearer way the author could have presented the information? In what ways...

The three main measures of central tendency are the mean, median, and mode. Each of these could be impacted in different ways by an outlier that is distant from the other data points. Depending on the data set that you are describing, you might choose to use the mean, median, or mode to give a more accurate view of the data. Describe a situation where you might have an outlier in a data set. How will this outlier impact the...

The mean, median, and mode are frequently referred to as the measures of central tendency. All three of these are used commonly, especially by the media when trying to make a point or persuade an audience to some point of view. However, each of these three statistical measures has their own shortcomings.
