Central tendency will only give you information on the location of the data. You also need dispersion to define the spread of the data. In addition, shape should also be part of the defining criteria of data. So, you need: location, spread & shape as best measures to define data.

Why is central tendency important?
Because it measures the averages of a collection of data
Which statements accurately describes the measures of central tendency?

What measures of central tendency are appropriate for the variable for gender?
mode
When is it the most appropriate time to use b Measures of Central Tendency?

What is the difference between the measures of central tendency and the measures of dispersion?
difference
Are measures of central tendency complement to measures of dispersion?

What do you mean by measures of central tendency and dispersion?
Common measures of central tendency are the mean, median, mode. Common measures of dispersion are range, interquartile range, variance, standard deviation.
Which measures of central tendency become larger as the data is more dispersed?
None. Measures of central tendency are not significantly affected by the spread or dispersion of data.
Why is range not a measure of central tendency?
Measures of central tendency are averages. Range , the difference between the maximum and the minimum, is a measure of dispersion or variation.
Why are three different measures needed in math measures of central tendency and dispersion?
There are more than three measures. Some are better than others in some situations but not as good in other situations.
What is dispersion method?
It is the measure of central tendency.
Why is central tendency important?

no it is a measure of dispersion.
How do we obtain useful information from a set of data?
You calculate summary statistics: measures of the central tendency and dispersion (spread). The precise statistics would depend on the nature of the data set.
Which statements accurately describes the measures of central tendency?
"Measures of central tendency are statistical measures." is an accurate statement.
What is the difference between range and spread in mathematics?
In Statistics, the measure of spread tells us how much adata sample is spread out or scattered. We can use the range and the interquartile range (IQR) to measure the spread of a sample. Measures of spread together with measures of location (or central tendency) are important for identifying key features of a sample to better understand the population from which the sample comes from. The range is the difference between a high number and the low number in the samples presented. It represents how spread out or scattered a set of data. It is also known as measures of dispersion or measures of spread.
