Mary's quiz scores were 92 85 78 92 71 77 and 80 she told her mom she had an average score if 92 for her quiz scores.which term best Describes Her Average Score ? Mean median mode or range please answerđ
To find the best term that describes Mary's average score, we need to calculate the different measures of central tendency: mean, median, mode, and range.
Mean: The mean is calculated by summing all the values and dividing the total by the number of values. In this case, the mean is calculated as (92 + 85 + 78 + 92 + 71 + 77 + 80) / 7 = 575 / 7 â 82.14.
Median: The median is the middle value when the numbers are arranged in ascending or descending order. In this case, when you arrange the scores in ascending order, it becomes 71, 77, 78, 80, 85, 92, 92. The middle value is 80, which is the median.
Mode: The mode is the value that appears most frequently. In this case, all the scores appear only once, so there is no mode.
Range: The range is the difference between the highest and lowest values. In this case, the lowest score is 71, and the highest score is 92. So, the range is 92 - 71 = 21.
From the calculations:
- The mean score is approximately 82.14.
- The median score is 80.
- There is no mode.
- The range is 21.
Therefore, the best term that describes Mary's average score would be the mean.
