Use the one that best suits your data. Measures of Central Tendency These are statistical terms that try to find the "center" of the numbers that are in a group of data.
Once we know this, we can measure the amount of dispersion or spread of the data values from the typical, central, value. While the mean, mode, and median represent centers of data, one is usually more helpful than another when talking about a particular data set.
When the data forms a U-shaped symmetrical distribution, the midrange is the preferred measure of center. The measures we consider here are percentiles and quartiles. The Mean.
Measures of variability are statistical procedures to describe how spread out the data is. Although the measures of center did approach the question differently, they do attempt to measure the same point in the distribution and thus are comparable.. You can think of it as the tendency of data to cluster around a middle value. Answer: Half-way between, which is 5. . The standard deviation measures the spread in the same units as the data. complete set of data. Range. Instant Center Lenth: 52.76". With just 2 numbers the answer is easy: go half-way between. The same method is also used by the TI-83 to calculate quartile values. examples. However, for a dataset that has a skewed histogram (for example with a long right tail):
