24 - 16.642 = 7.3579 - 16.642 = 7.642

25 - 16.642 = 8.35724 - 16.642 = 7.357

11 – 16.642 = 5.642…etc

7.357 x 7.357 = 54.1277.642 x 7.642 = 58.4138.357 x 8.357 = 69.8417.357 x 7.357 = 54.127

54.127 + 58.413 + 69.841 + 54.127 + 31.841 +

74.698 + 6.984 + 11.270 + 58.413 + 0.413 +

69.841 + 2.698 + 21.556 + 18.984 = 533.2143

533.2143 / 14 = 38.086

Then you find the square root of that number to find the

Standard Deviation

√38.086 = 6.171
