  1. A class recorded the following test scores: 70, 85, 90, 85, 75, 85, 60. What is the mode?

    Answer: 85

    The mode is the value that appears most often; 85 appears three times, more than any other score.

  2. On a bar graph showing student test results, the x-axis represents subject names. What does the y-axis most likely represent?

    Answer: Number of students or scores

    In a bar graph with subjects on the x-axis, the y-axis typically shows the numerical value, such as number of students or test scores.

  3. What is the median of the data set: 4, 7, 10, 13, 19?

    Answer: 10

    The median is the middle value when data is ordered; in this set of 5 numbers, the middle (3rd) value is 10.

  4. A pie chart shows that 40% of students prefer math and 35% prefer reading. What percentage prefer other subjects?

    Answer: 25%

    Since all percentages in a pie chart must total 100%, the remaining percentage is 100 − 40 − 35 = 25%.

  5. Which measure of central tendency is most affected by an extremely high or low value (outlier)?

    Answer: Mean

    The mean is calculated using all values, so an outlier significantly changes the average, while the median and mode are less affected.

  6. A line graph shows temperature each month for a year. Which conclusion can best be drawn from a line graph?

    Answer: How temperature changes over time

    Line graphs are best for showing trends and changes over time, making them ideal for tracking monthly temperature.
