Enter your HR values in exactly the order they appear on the Data Record. - Mean: Calculate the Sum of X (ΣX) and the mean. Formula for the mean is: Mean = µ = Remember: N is the number of data points in your data set. → Report the mean with one decimal. Do not show calculations. - Deviations: Calculate the deviation (X-µ) value for each X. (→ Order matters! X - Mean) These ‘deviations’ or ‘deviation scores’ indicate the distance between each value (or ‘score’) and the mean. → Error Check: The sum of the deviations should be zero. - Median: Use the simple method shown in the text and notes. Report to one decimal. - Mode: Report the mode(s). → If there is no mode, answer ‘no mode,’ not N/A or 0. N/A is unspecific, and if your most frequent HR is zero, you are in real trouble!!)
