# In a symmetrical distribution with a mean of 15 the median would be

When n is even, the median is the mean of the two middle values. 4. Example Suppose we have the following series: 15, 19,21,7, 10,33,25,18 and 5 Solution We have to first arrange it in either ascending or descending order. 1-Symmetrical Distribution When a distribution is symmetrical, the mean...

The mean will be about the same as the median, and the box plot will look symmetric. If the distribution is skewed to the right most values are 'small', but there are a few exceptionally large ones.

Also unique about the normal distribution curve is that the mean, median, and mode are the same value. When looking at any graph, you can estimate the mode and median by simply looking at a graph: the mode is the value with the highest frequency, and the median is the middle point.

When the distribution is not symmetrical (often described as skewed), the mean and the median are not the same. • For symmetrical distributions, the mean is an appropriate choice for describing a typical value for the distribution. For skewed data distributions, the median is a better description of a typical value.

Mean, median, and mode are values that are commonly used in basic statistics and in everyday This means that at least two numbers appear the greatest amount of times in the distribution. If the set is made of an odd number of integers, the median will be the middle number, and if it's an even...

Answer: 15.0. To find the median, put the numbers in order from smallest to largest: 4, 5, 6, 12, 15, 16, 18, 20, 22. Because this data set has an odd number of values (nine), the median is simply the middle number in the data set: 15. To the nearest tenth, what is the median of the following data set? 14, 2, 21, 7, 30, 10, 1, 15, 6, 8. Answer: 9.0

A distribution in which the values of mean, median and mode coincide (i.e. mean = median = mode) is known as a symmetrical distribution. In moderately skewed or asymmetrical distribution a very important relationship exists among these three measures of central tendency.

Mean refers to the average amount in a given group of data. In this measure of central tendency, all the data are added up and then divided by the number of figures in the data in order to ascertain the mean. Median is the middle most value of a series. Mode is the highest occurring figure in a series.
