A mathematical outlier, which is a value vastly different from the majority of data, causes a skewed or misleading distribution in certain measures of central tendency within a data set, namely the mean and range, accord... More »

According to Oxford University's Medical Sciences Division, the mean is the average value of a group of numbers, the median is the middle value in an ordered list of values and the mode is the most common number that app... More »

The mean, median and mode are different methods to determine the average of a set of integers. Though all three methods are used to compute an average, each result could differ. More »

The measures of central tendency refer to the mean, median and mode. These statistical figures help to determine a central or typical value for a particular parameter. Mean, median and mode are all different, and it is i... More »

Mean, median and mode are different ways of determining the average from a set of numbers. Range gives the difference between the highest and lowest values. More »

The interquartile range, or IQR, can be found after the median has been determined by dividing the data sets that are above and below the median in half, which divides the entire set into quarters, and then combining the... More »

Modal value refers to the mode in mathematics, which is the most common number in a set of data. For example, in the data set 1, 2, 2, 3, the modal value is 2, because it is the most common number in the set. More »
