Assessment 1 Instructions: Descriptive Statistics

  • Use IBM SPSS to create, interpret, and analyze two histograms in a Word document.Descriptive statistics are just what they sound like, statistics that allow you to describe or summarize the data with regard to such things as their distribution and their spread. Descriptive statistics provide you with a picture of your data while inferential statistics (which we will discuss in subsequent assessments) allow you to draw conclusions about relationships between variables or differences between groups.A solid understanding of descriptive statistics is foundational to grasping the concepts presented in inferential statistics. This assessment measures your understanding of key elements of descriptive statistics.Your first IBM SPSS assessment includes two sections in which you will do the following:
    1. Create two histograms.
    2. Calculate measures of central tendency and dispersion.

    This will give you some experience with the data set.

    KEY DETAILS AND INSTRUCTIONS

    The grades.sav file is a sample SPSS data set. The data represent a teacher’s recording of student demographics and performance on quizzes and a final exam. For this assessment, you will create and describe two histograms and a descriptives table using these data.

    SECTION 1: HISTOGRAMS FOR VISUAL INTERPRETATION

    Using the final and gender variables in your grades.sav data set, create two histograms and paste them into your Word document:

    SPSS Variables and Definitions
    SPSS Variable Definition
    Gender female =1; male =2
    Final final exam: number of correct answers

    Create:

    • A histogram for male students.
    • A histogram for female students.

    In addition, briefly describe what a visual inspection of this output tells you about the nature of the curves.

    SECTION 2: CALCULATE MEASURES OF CENTRAL TENDENCY AND DISPERSION

    Using the grades.sav file, compute descriptive statistics, including mean, standard deviation, skewness, and kurtosis for gpa and quiz3.

    SPSS Variables and Definitions
    SPSS Variable Definition
    GPA Previous grade point average
    Quiz3 Quiz 3: number of correct answers

    Create one descriptive table for GPA and quiz3. In addition, briefly describe what skewness and kurtosis tell you about these data with regard to normality.Submit both sections of your assessment as an attached Word document. Refer to the Copy/Export Output Instructions [PDF] for guidance.

    SOFTWARE

    The following statistical analysis software is required to complete your assessments in this course:

    • IBM SPSS Statistics Standard or Premium GradPack, version 24 or higher, for PC or Mac.

    COMPETENCIES MEASURED

    By successfully completing this assessment, you will demonstrate your proficiency in the course competencies through the following assessment scoring guide criteria:

    • Competency 4: Interpret the results of statistical analyses.
      • Provide accurate interpretation of histograms for males and females.
      • Provide accurate interpretation of measures of central tendencies.
    • Competency 5: Apply a statistical program’s procedure to data.
      • Provide histograms for males and females.
      • Provide measures of central tendencies?.
