If the mean of a numerical data set exceeds the median, the data are considered to be left-skewed.
举一反三
- The arithmetic average of a set of data is known as its . A: mean B: median C: precision D: experimental result
- The measure of location which is the most likely to be influenced by extreme values in the data set is the ( ) A: range B: median C: mode D: mean
- In a set of numerical data, the value for Q2 is always halfway between Q1 and Q3.
- In a set of numerical data, the value for Q3 can never be smaller than the value for Q1.
- The median of a data set with 20 items would be the average of the 10th and the 11th items in the ordered array.
