一、代表不同 1、mean翻译：均值，通常指算术平均，也可以是几何平均。叙述：把一组序列中的所有值加起来，然后除以总个数，就是均值。2、median翻译：中间值。叙述：把一组序列按照升序的方式排列，然后取中间的那个值，就是中间值。3、average翻译：均值，通常指算术平均。叙述：通常用来形容优劣难分...
You find themean(informally called theaverage) by adding up all the numbers in a set and then dividing by how many values there are. When you arrange a set of values from smallest to largest, themedianis the one in the middle. Themodeis simply the value that occurs the most in the s...
“均值”和“平均值”在中文语境下通常可以视为同一个概念，都表示一组数据的总和除以数据的个数所得...
The descriptive statistics most commonly tested on the GMAT are the three main types of average, more formally known as “measures of central tendency”: the arithmetic mean or common average, the median, and the mode. We’ll start with a discussion of the mode....
The Mean, Median, and Mode represent three different ways of finding the “Average” value for a group of numbers. Often the “Median” or Middle value is used to express an Average for cases where there can be large variations in values at the high and low ends of the group. ...
We can see that the arithmetic average is exactly the same for the three ($57,705.88), the median varies significantly (from $23,000 to $49,000), and so does the mode. For two of the companies the median is equal to the mode. In many cases, we would find the median to be the...
The mean is the average of a data set. The mode is the most common number in a data set. The median is the middle of the set of numbers. Of the three, the mean is the only one that requires a formula. I like to think of it in the other dictionary sense of the word (as in...
mean: regular meaning of "average" median: middle value mode: most often (In the above, I've used the term "average" rather casually. The technical definition of what we commonly refer to as the "average" is technically called "the arithmetic mean": adding up the values and then dividing...
When there is an even number of values, you count in to the two innermost values and then take the average. The average of 27 and 29 is 28. Consequently, 28 is the median of this dataset. Outliers and skewed data have a smaller effect on the median than the mean as a measures of ...
