Answer

c. mean = 75.8, median =76.5, mode = 63


Explanation

Mean, meadian and mode are called the values of central tendancy. The help us study a set of data more clearily.

mean = total value/total frequency

          =(88+89+65+62+83+63+84+63+74+64+71+82+66+88+79+60+86+63+93+99+60+85 ) ÷ 22

  = 1667/22

  = 75.8

Median is the value at the center of the data when arranged in ascending order.

60,60,62,63,63,63,64,65,66,71,74,79,82,83,84,85,86,88,88,89,93,99

median = (74 + 79)/2

            = 153/2

              =76.5

Mode is the value that occurs many times in the data.

Mode = 63

The mean, median, and mode of the data distribution to the nearest tenth are: c. mean = 75.8, median =76.5, mode = 63

What is the Mean, Median, and Mode of a Data Distribution?

  • The mean = average score = sum of all the scores divided by number of scores in the data distribution.
  • Median of a distribution is the data value that lies at the middle when the data is ordered.
  • Mode is the data value that appears the most in a distribution.

Mean of the data distribution:

Mean = 75.8

Median of the data distribution:

Median = (74+79)/2 = 76.5

Mode of the data distribution:

Mode = 63

Thus, the mean, median, and mode of the data distribution to the nearest tenth are: c. mean = 75.8, median =76.5, mode = 63
