use this data to do the following:

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