Seetha, the receptionist of Mind Zone – a mind game center, recorded the number of visitors per day in her logbook and calculated the average per week. While doing the monthly updates she noticed that the data on a particular day is missing as water spilled over it.

What would be the missing value?

Since Seetha calculated the average number of visitors per week, the missing value is the average multiplied by 7,  less the total of the non-missing values.

How is a missing value calculated from an average number?

If a number is missing from an average number, we can find the missing number by following these steps:

  1. Add the non-missing numbers.
  2. Multiply the mean or average by the total number of variables (e.g. number of days in a week).
  3. Subtract the value of the non-missing numbers from the sum in (2) above.

Thus, since Seetha calculated the average number of visitors per week, the missing value is the average multiplied by 7,  less the total of the non-missing values.
