Analyze Math Quiz Data

Using these same data about the math quiz, answer the following questions.

{6, 1, 0, 2, 3, 4, 3, 1, 2, 6, 3, 5}

  • What is the sum of the values in the data set?
  • How many data values are there?
  • Find the mean of the data.
  • Use either the list of values in the data set or your line plot to answer these questions:
    • What is the lowest score? What is the highest score? The difference between the lowest score and highest score is called the range.
    • Which score occurs most often? The score that occurs most often is called the mode.
    • Which score is in the middle of the data? The middle value is called the median.
    • Which score makes up the middle 50 percent of the data?
    • What do you think the typical score is?

Hint:

To find the mean, add up all the data values and divide by the number of data values.
