Measures of Central Tendency and Variation Cover sheet, Measures of Central Tendency Cover Sheet, Measures of Variation Cover Sheet The best measure of center depends on the distribution of the data. 2. In addition to the mean and the median, there is one other common measurement of the "typical" value of a data set: the mode. The most elementary measure of variation is range. When the standard deviation is low, it implies that most of the values are near the mean. 6 different measures of central tendency and variation checklists (Mean, median, mode, range, IQR and MAD) Measures of Central Tendency & Variability - Online Math Learning The two most widely used measures of the "center" of the data are the mean (average) and the median.

The number of pages that Carolyn wrote in her journal each day from Monday to Friday is shown below: 9, 8, 12, 6, 10. Variability helps you to understand the variation in a sets of numbers. In each case, there are 10 values, so the median is the mean of the 5th and 6th values. Looking at the maximum value for those that died and the third quartile of the survivors, we can see that over 25% of the survivors had birth weights higher than the heaviest infant that died. The lower half has 50 values, so Q1 is the mean of the 25th and the 26th values. RANGE = MAXIMUM - MINIMUM Since the range only uses the largest and smallest values, it is greatly affected by extreme values, that is - it is not resistant to change. The mode is the data value that occurs most often. All three of these sets of data have a mean of 5 and median of 5, yet the sets of scores are clearly quite different.
