You can interpret a histogram with 1) Shape 2) Center 3) Spread To measure the center we need to measure: ➔ Mean ➔ Median ➔ Mode All depending on what kind of data is recorded For a symmetric graph the center is: Mean and Median and they are equal For a Right Skewed graph the center is: Mean is to the right and Median is centered For Left Skewed graph the center is: Mean to the left and the median is centered Mean: algebraic average 7, 8 7 + 8 = 15 ➗ 2 ( total number of data ) 7.5 Mean (summation symbol): ∑x 一
