of the correlation coefficient also known as "r" in statistics. The value "r" can result in anegative numberbut r2 can't result in a negative number because r-squared is the result of "r" multiplied by itself or squared. The square of a negative number is always a positive value.2 ...
If there are even numbers of values, we calculate the mean of the values in the middle to find the median. Median = (4+6)/2 = 10/2 = 5 Mode The mode of a data set is the value appearing most often in the set. Mode formula Mode = Most occurring value Let’s consider the ...
