Q
mean mode median range
A
. Mean: the average, which is found by adding up all the values in a set of data and dividing it by the total number of values you added together.
. Median: the middle number in the set of values. You find it by putting the numbers in order from the smallest to largest and covering up one number on each end until you get to the middle.
. Mode: the number or value, which appears most often in the set. To find the mode, you need to count how many times each value appears.
. Range: the difference between the lowest and the highest value. To work it out, simply subtract the lowest value from the highest.
