use this data to do the following:

  1. 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.
  2. Discuss which measure of central tendency you think most accurately describes the variable that you measured. Provide a thorough explanation.
  3. 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.
  4. Conduct a scholarly search on the internet to find reported health statistics on the variable that you are measuring. For example, if you are measuring your total daily caloric intake, American Dietetic Association. Identify the source.

Submit your (2-3 pages) paper by the end of this module.

Question 1: Measure of Central Tendency
Mean,
The mean is the average of the sum of all the data in the group. Thus, the mean is the sum of all
the data collected divided by the number of data observed (The Johns Hopkins University &
McGready, 2009).

= 25 + 22 + 28 + 32 + 32 + 30. = 137/5 = 27.4
Median,
To find the median value, the data is arranged in order from the smallest value to the largest
value. Then the data that falls at the center of the group data is considered as the media value
(The Johns Hopkins University & McGready, 2009).
Hence, the median value is given by
22, 25, 28, 30, 32, hence, the median value is 28
Mode,
The mode is the data that appears more than one in the group statistics. In this case, there
is no modal value in the data because each data only appears once. Thus, the frequency of each
data was only observed once (The Johns Hopkins University & McGready, 2...
