Navneet: Week 1 - Lab 1

EXAMPLE. The spreadsheet below contains fish length data for two populations, Aquarium and Coral Reef. Download the spreadsheet and complete the following tasks, as well as answer the following questions:

• Tasks:
  • Sort the data of the two populations in ascending order
  • Calculate the min, max, count, average, median, mode, and standard deviation of each population
• Questions:
  • What is the relation between the averages of the two populations?
  • What is the standard deviation of each population?
  • What is the range (min and max) and median of each population, and what is the relation of these values to the standard deviation of the their respective population?
  • What is the mode of each population?
    • How does Excel handle the case when there is more than one solution (hint: look at the ascending order of the data)?
    • Create an example data set with no repeating numbers. When calculating the mode in this scenario what does Excel return?
