PROBABILITY ASSIGNMENT INSTRUCTIONS
OVERVIEW
This assignment is designed to increase your understanding and proficiency in conceptualizing
and computing the probability of simple events as well as the probability of certain outcomes
using the z score and the normal distribution. A working knowledge of these concepts, along
with what you will learn next week, will help you make the important transition from working
with descriptive statistics to working with inferential statistics. Inferential statistics form the
backbone of social science research, and having a solid understanding is essential to conducting,
interpreting, and applying research in your chosen field.
INSTRUCTIONS
To access the homework problems for this assignment, please download the Probability
Template document linked on the Probability Assignment page.
This assignment includes several problem sets related to probability and the proportion of
scores under the normal curve related to specific z scores.
For each scenario, you will compute your answer using a calculator or pencil and paper.
Typewritten answers into the document in the specified answer spaces. Please keep the
red font formatting for answers and show work when directed to do so. You may type
your work, use a stylus/e-pen, or write it by hand and scan the results into a finished
document. Be sure all work is legible.
Please review the Demonstration Video: Finding Proportions and Percentile Ranks, as well
as Chapter 6 in your textbook, for procedures related to solving these problems
