The median is the number that falls in the exact center of all the measurements, while the mode is the number that occurs most frequently. There are several ways to measure variability, or the amount of spread in a set of data.

Why is the measure of center important? Measures of center are some of the most important descriptive statistics you can get. In our society, we always want to know the "average" of everything: the average age, average number, average speed, etc.etc. It helps give us an idea of what the "most" common, normal, or representative answers might be.

What are the measures of variation and what are they used for? Measures of variation are used to describe the distribution of the data. The range is the difference between the greatest and least data values. Quartiles are values that divide the data set into four equal parts. The median of the lower half of a set of data is thelower quartile or LQ; in this case, 1.

What is average standard deviation? To calculate the standard deviation, you need to determine the variance: Find the mean, or average, of the data points_by adding them and dividing the total by the number of data points. Find the average of each of those squared differences. The standard deviation is simply the square root of the resulting variance.
