Mean, Median, and Mode of Dental Office Patients


Mean


  • The mean is also known as the average.

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

  • In this case, add up the number of patients treated in the dental office on Monday for the 11 weeks.

  • Then divide the sum by 11 to get the mean.



Median


  • The median is the middle value in a dataset when the values are arranged in numerical order.

  • To find the median, arrange the values in numerical order and find the middle value.

  • If there are an even number of values, find the average of the two middle values.



Mode


  • The mode is the most frequent value in a dataset.

  • To find the mode, count how many times each value appears in the dataset.

  • The value that appears the most is the mode.

  • If there are multiple values that appear the same number of times, then there is no mode.



Explanation and Calculation


  • Let's assume the number of patients treated in the dental office on Monday for 11 weeks are: 10, 12, 12, 15, 16, 17, 18, 20, 22, 25, 30.

  • Mean = (10+12+12+15+16+17+18+20+22+25+30)/11 = 187/11 = 17.

  • Median = 16 (arrange values in numerical order and find the middle value).

  • Mode = 12 (appears twice in the dataset, which is more frequent than any other value).
