1 Hand calculate the Standard Deviation for RESTING HEART RA

1. Hand calculate the Standard Deviation for RESTING HEART RATES below (using instructions provided):

a. Add scores (sum)

b. Calculate mean

c. Subtract mean from each score (individual deviation)

d. Square individual deviations

e. Add squared deviations

f. Divide sum of squared deviations by N (sample size) (VARIANCE)

g. Take square root (STANDARD DEVIATION)

2. Calculate the z-Score for the person with an 85 Resting Heart Rate (using this equation). What does it mean (use curve on next page)?

z= Value-Mean/Standard Deviation

3. Using the DESCRIPTIVE STATISTICS SPREADSHEET, run Descriptive Statistics on Weeks 4 and 8 and discuss your findings.
