Descriptive Statistics Assignment

Assignment Preparation

This unit provides context for an upcoming assignment on histograms and descriptive statistics in Unit 3. Look ahead at the instructions and scoring guide for the Unit 3 assignment so that you have it in mind as you study the materials and complete the activities in this unit.

Software Installation

Make sure that IBM SPSS Statistics Standard GradPack is fully licensed, installed on your computer, and running properly. It is important that you have either the Standard or Premium version of SPSS that includes the full range of statistics. Proper software installation is required in order to complete your first SPSS data assignment in Unit 3.

Next, click grades.sav to download the file to your computer.

•Important: Do not use the original George and Mallery grades.sav file, as the course room grades.sav is modified for 7864.

You will use grades.sav throughout the course. The definition of variables in the grades.sav data set are found in Chapter 1 of your IBM SPSS Statistics Step by Step text. Understanding these variable definitions is necessary for interpreting SPSS output.

Next week, you will define values and scales of measurement for all variables in your grades.sav file.

Histograms and Descriptive Statistics

Your first IBM SPPS assignment includes two sections in which you will:

Create two histograms and provide interpretations.
Calculate measures of central tendency and dispersion and provide interpretations.
