Assignment:
Introduction
You will be doing some basic statistics on the data you collect for your research project. This assignment is designed to get you used to doing the statistical calculations you will need to do for your final project.
Activity Instructions
Create another separate Word document with "worksheet" as the title and include your last name in the title as well. Then answer the questions in the worksheet in the separate document. Make sure to number your answers so they can be matched up with the correct questions.
Directions: For this assignment complete the work sheet below. Please type out your answers on a separate Word document and then upload it. Don't forget to number your answers so they can be matched up to the correct question.
1. People were asked how many miles they lived from work. The responses were 22, 20, 1, 25, 35, 23, 18, 5, 22, 22, 15, 7, 14, 21, 5, 9 and 13. The national average distance from work is 20 miles. Find the following:
a) Mean
b) Median
c) Mode
d) Standard deviation
e) Z-Score
f) Range
What would be the most appropriate measure of central tendency and why? Does this data represent a skewed distribution? Why or Why not?
2. At a pet store, a survey was taken asking how many pets each person had. The results were: 2, 5, 3, 1, 0, 4, 2, 7, 0, 2, 5, 1, 2, 6, 2, 10, 7, 3. The population average is 2. Find the following:
a) Mean
b) Median
c) Mode
d) Standard deviation
e) Z-Score
f) Range
What would be the most appropriate measure of central tendency and why? Does this data represent a skewed distribution? Why or Why not?
3. A sample of eight students were randomly selected and asked, "How many times did you check your email yesterday?" The numbers were: 3, 0, 8, 7, 10, 2, 6, 12, 45, 82, 1, 23, 11, 4, 55, 0.The average number of email checks in the population is 16.
a) Mean
b) Median
c) Mode
d) Standard deviation
e) Z-Score
f) Range
What would be the most appropriate measure of central tendency and why? Does this data represent a skewed distribution? Why or Why not?
