correlationA pattern where two quantities tend to change together: both rise, or one falls as the other rises. It does not prove that one causes the other.
You’ll leave with these skills
01Find the mean of a data set with repeated values in DesmosType the numbers into a Desmos list in square brackets, repeats included, then type mean with the list’s name in parentheses.
02Find the mean or median of a frequency tableType the values and their counts as two lists, then type repeat with both lists to build the full data set before finding the mean or median.
03Tell which of two data sets is more spread outType each data set as a list, type stdevp of each one, and pick the list with the larger result.
04Read a median or range straight from a short listOrder the numbers. The median is the middle value for an odd count, or the average of the two middle values for an even count. The range is the largest value minus the smallest.
