    Exam Reports

    Sample report shows an 8-question exam taken by 10 students.
    Peter Cottontail failed to answer Question 3.
    Six reports are produced.

    Student Response Report - see sample report

    Answer key listed in first row.
    Provides:

    • Student’s name and ID number
    • Identifies visually what questions student answered correctly (green), incorrectly (red), or failed to answer (white)
    • Total score for student
    • Student’s percent score (of correct responses)
    • Percent correct for the question (last row)

     

    Student Statistics Report - see sample report

    Relates to previous TEST RESULTS report.
    Provides:
     

    • Student’s name and ID number
    • Student’s total score (6.00 / 8.00 means student answered 6 out of 8 questions correctly)
    • Student’s percent correct for exam
    • Z Score - Indicates how many standard deviations a score is above or below the mean (symbolized by + and -)
    • T Score - A converted Z score used to convert scores that are negative, fractional or both. The T score can be expressed as 10z + 50.
    • Number correct
    • Number incorrect
    • Number missing
    • Means appear in the last row

     

    Condensed Item Analysis Report - see sample report

    Relates to previous ITEM ANALYSIS report.
    Provides for each question:
     

    • Response frequency and percent
    • Correct response indicated by an asterisk *
    • Number of students who failed to answer the question (Missing designation)
    • Correct percentage shown in green on bar chart
    • Incorrect percentage shown in red on bar chart
    • If an answer was chosen more than the correct answer (distractor), it is shown in yellow on bar chart

     

    Three reports are provided to approximate the information given in the previous GRADE DISTRIBUTION report.

    They are Test Item Statistics Report, Test Statistics Report, and Condensed Test Report.

    Test Item Statistics Report - see sample report

    Provides for each question:

    • Points for question (always 1.0)
    • Number of students graded
    • Number of students with correct answer
    • Number of students with incorrect answer
    • Number of students who failed to answer question
    • Point Biserial - A measurement of the discrimination of an item. It indicates the relationship between a response for a given item and the overall test score of the respondent. The point biserial tells you if a question was a good discriminator between the better students and the poorer students. Point biserial ranges from -1 to 1. A positive value indicates that the students who did well on the test answered the question correctly.
    • Percent Correct

     

    Test Statistics Report - see sample report

    Provides information for the exam as a whole:

    • Score Data
      • Number of graded items
      • Total points possible
      • Maximum score
      • Minimum score
    • Statistics
      • Mean score
      • Mean percent score
      • Benchmark score (not applicable)
      • Range of scores - distance between the highest and lowest score
      • Standard deviation - measure of the dispersion of a set of data from its mean. The more spread apart the data is, the higher the deviation. It is calculated by taking the square root of the variance.
      • Variance - The amount that each score deviates from the mean squared (by multiplying it by itself).
    • Percentiles
      • 25th Percentile - 25 percent of the data values lie below the 25th percentile
      • Median score
      • 75th percentile - 25 percent of the data values lie above the 75th percentile
      • Inter Quartile Range - The difference between the 75th percentile and the 25th percentile
    • Confidence Intervals (1, 5, 95, and 99%)
    • Test Reliability
      • Kuder-Richardson Formula 20 & Kuder-Richardson Formula 21 - These formulas measure test reliability and are an overall measure of internal consistency. A higher value indicates a stronger relationship between items on the test.
      • Coefficient (Cronbach) Alpha - A coefficient that describes how well a group of items focuses on a single idea or construct.

     

    Condensed Test Report - see sample report

    Provides some overall statistics and then provides statistics on individual questions:

    • Overall
      • Total possible points
      • Total students
      • Standard deviation
      • Median score
      • Mean score
      • Reliability Coefficient (KR20) - a higher value indicates a stronger relationship between items on the test
      • Maximum score
      • Minimum score
      • Range of scores -- difference between max and min
    • Question Statistics
      • Correct answer
      • Response frequencies (percentages)
      • Non distractor (question choices not selected by students)
      • Correct group responses - The TOTAL% column displays the percentage of students who answered the question correctly. The UPPER 27% column displays the percent correct for the individual question based on the students who scored in the upper 27% for the test as a whole. The LOWER 27% column displays the percent correct for the individual question based on the students who scored in the lower 27% for the test as a whole.
      • Point Biserial -- A measurement of the discrimination of an item. It indicates the relationship between a response for a given item and the overall test score of the respondent. The point biserial tells you if a question was a good discriminator between the better students and the poorer students. Point biserial ranges from -1 to 1. A positive value indicates that the students who did well on the test answered the question correctly.
