Mean and median both try to measure the central tendency in a data set. When used in conjunction with a measure of center the spread can more fully describe a set of data.

A center is a point that is the same distance from all the extremities of a figure. The figure below would be called the circle C. Two measures of center are mean and median.

Two measures of spread are range and standard deviation. They are the mean the median and the mode. The median is the number that is in the middle when the data is ordered from least to greatest and the mode is the number that appears most often.

You may need to find the mean of two middle values. So the mean is. The center point is often used to label the whole circle.

Measures of central tendency represent the central position of a set of data. To find the median count the dots from left to right until you find the middle value. The four measures of center are mean median mode and midrange.

For example a mean may not be the best representative of a sample when the spread is very large due to the differences across the set. Measure from center of one lug stud that the lug nut bolts on to to the center of the lug directly across from it if you have four- six- or eight-lug hubs. The goal of each is to get an idea of a typical value in the data set.

Giving quantitative measures of center median andor mean and variability interquartile range andor mean absolute deviation as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered. A measure of central tendency measure of center is a value that attempts to describe a set of data by identifying the central position of the data set as representative of a typical value in the set.

1 03 16 23 32 41 51 61 71 11 19. It is calculated by taking all of the values in a set and dividing them by the total number of values in that set. The most common method for measuring the center is the mean an average of the data.
