Unformatted text preview: BMI score for 15 24.09, 23.04, 24.19, 23.19, 25.65 = (24.09+23.04+ 24.19+ 23.19+ 25.65)/5 = (120.16)/5 = 24.032 See Excel Sheet 5. Calculate the Standard Deviation (SD) of the first 5 people’s BMI scores using the definitional formula (text page 38.) Calculate the Standard Deviation of everyone’s BMI and 1 RM bench press using EXCEL. Calculate the SD for the BMI for your section using EXCEL. SD =√ [∑ (x mean) 2 ]/ (n1) ∑X =120.16, ∑(Xmean)=0, ∑(Xmean) 2 =4.339 = √ 4.339/(51) = √ 1.08475 = 1.0415 See Excel Sheet 6. Calculate the Standard Error of the Mean for the BMI scores for the whole class. Within how many SEs of the mean does your section’s mean fall? SEM= SD/ √n, SD=3.33, n=107 =3.33√107 =3.33/10.34408 = .3219 My section’s mean falls within 1 SE of the overall mean. 23.21+.3219=23.53, 23.21.3219=22.89. My section’s mean is 23.44 and falls in the range of 22.89 to 23.53. Brittany Haynes Kin 3502 Section 5 11/17/10...
