Calculate and describe measures of central tendency (mean, median, and mode), variance, and standard deviation of given data.

  Monday Tuesday Wednesday Thursday Friday
Cardio 35 40 rest 60 0
Weight 35 20 rest 0 60

70                           60                                           0                              60                           60

Calculate the mean, median, mode, variance, and standard deviation of the measurements taken in Module 1 SLP. Show your work and be sure to express each value in units.

Mean-      70+60+0+60+60 = 50

N=5

Median- 70, 60, 0, 60, 60= 0, 60, 60, 60 70=60

Mode is 60 since it’s the number that repeats the most out of all the data.

Variance = 800

Standard deviation is 28.28

Variance- = =

Discuss which measure of central tendency you think most accurately describes the variable that you measured. Provide a thorough explanation.

Out of the median, mean and mode, one can say mean is the most accurately way to describe the variables that were measured. The reason that the medium would not work is because not all the numbers are closest to 60. On Wednesday no exercise was completed. Same happens with mode. “Another problem with the mode is that it will not provide us with a very good measure of central tendency when the most common mark is far away from the rest of the data in the data set” (Measures of Central Tendency).Even though the number 60 repeats itself many times, it is still too far from the 0 minutes completed on Wednesday. The mean result is 50. This is closest one to all the numbers from the data collected.  [“Write my essay for me?” Get help here.]

 

Describe the spread/distribution of your data. Be sure to describe the variance of distribution and the concept of standard deviation as a measure of dispersion in your response.

            The data that was collected was over a period of 5 days. “An important attribute of the standard deviation as a measure of spread is that if the mean and standard deviation of a normal distribution are known, it is possible to compute the percentile rank associated with any given score” (Standard Deviation and Variance).The standard deviation was 28.28.[Click Essay Writer to order your essay]

 

Conduct a scholarly search on the internet to find reported health statistics on the variable that you are measuring.

Data that was collected over a one week period displays the amount of time that was spent working out. The work out time was performed from Monday through Friday. Adding up all the days times, it equals to a total of 250 minutes or 4 hours and 10 minutes. According to the Centers of Disease Control and Prevention, one should spend at least 150 minutes working out. The American Heart Association is also a good reference. “Staying active is one of the most important things a person can do to help curb obesity, lower your chances of heart disease and live healthy. The American Heart Association is working to help kids, families and communities live heart-healthy lives. Use this physical activity information to help you get active and stay active, for life” (American Heart Society). After looking at the data that the CDC provides on Americans that perform at least 150 minutes of exercise a week, one can determine that only half of the population engages in such.
