  1. A set of test scores is: 72, 85, 90, 68, 85, 92, 75. What is the mode?

    Answer: 85

    The mode is the value that appears most often; 85 appears twice while all others appear once.

  2. What is the median of the data set: 4, 7, 9, 12, 15?

    Answer: 9

    When arranged in order, the median is the middle value; the third value is 9.

  3. A bar graph shows that 15 students chose math, 10 chose science, and 5 chose art. What fraction of students chose art?

    Answer: 1/6

    Total students = 30; art fraction = 5/30 = 1/6.

  4. What type of graph is best for showing how data changes over time?

    Answer: Line graph

    Line graphs connect data points over time and clearly show trends and changes.

  5. A NeSA student's scores on 4 practice tests are 80, 90, 70, and 100. What is the mean score?

    Answer: 85

    Mean = (80 + 90 + 70 + 100) / 4 = 340 / 4 = 85.

  6. What is the range of the data set: 14, 22, 8, 35, 19?

    Answer: 27

    Range = maximum − minimum = 35 − 8 = 27.
