Descriptive Statistics 1 Unit 3 Assessment Jana S. Hardiman Herzing University MA 320: Statistics Professor Lori A. Simmons September 25, 2022

Descriptive Statistics 2 There were 108 men utilized in this study. The mean for their resting heart rates were 79 beats per minute. The mean gives us the average of the 108 participants resting heart rates. In the medical world, their average heart rates were within normal range. The normal range is 60 to 100 beats per minute (Laskowski MD, 2020) . This data can be seen in the summary results below. The mean for the post exercise heart rate was 90 beats per minute. Again, this is the average of the 108 male participants post exercise. Ninety beats per minute is a good heart. However, there are a lot of factors that are missing. For example: How long after they exercised did they record their heart rate? What are the ages of the participants? The missing information makes it hard to know if the heart rates are good or bad. Male Resting Heart Rate Mean 79.03241 Standard Error 0.754895 Median 78.6 Mode 74.8 Standard Deviation 7.845099 Sample Variance 61.54558 Kurtosis 0.295042 Skewness -0.39257 Range 41.1 Minimum 55 Maximum 96.1 Sum 8535.5 Count 108

Descriptive Statistics 3 Male Post Exercise Heart Rate Mean 89.69515 Standard Error 0.785279 Median 90.234 Mode 99.692 Standard Deviation 8.160859 Sample Variance 66.59961 Kurtosis 0.068476 Skewness -0.49061 Range 40.9 Minimum 65 Maximum 105.9 Sum 9687.076 Count 108 Ninety-Two females participated in the heart rate exercise. The mean was 81 beats per minute. This is within normal range. Normal range is 60 to 100 beats per minute (Laskowski MD, 2020) . The mean gave us the average heart rate of the 92 participants. Female resting heart rate Mean 80.4923 9 Standard Error 0.82682 5

Descriptive Statistics 4 Median 80.6 Mode 85.2 Standard Deviation 7.93062 3 Sample Variance 62.8947 8 Kurtosis 0.83114 9 Skewness - 0.60016 Range 37.3 Minimum 60 Maximum 97.3 Sum 7405.3 Count 92 The mean for the post exercise heart rate is 90 for the 92 females who participated. Unfortunately, it is hard to say if the data is within normal range. We are missing information as mentioned above. However, a good reference point for post exercise heart rate is the heart rate should drop after the first minute after finishing exercise (Schwartz, 2019) .

Descriptive Statistics 5 Female post exercise heart rate Mean 89.69515 Standard Error 0.785279 Median 90.234 Mode 99.692 Standard Deviation 8.160859 Sample Variance 66.59961 Kurtosis 0.068476 Skewness -0.49061 Range 40.9 Minimum 65 Maximum 105.9 Sum 9687.076 Count 92 The mean for both male and female pre-exercise are close in comparison. The female was 2 beats higher per minute that the males. Post exercise results were the same. This information is based off the mean of both pre and post heart rates for male and female. The standard deviation results indicated that the variation of the heart rates, at rest and post exercise, were close to the mean. In other words, there was not a lot of difference in the two results. Reference Laskowski MD, E. (2020, October 2). Whats a normal resting heart rate .
