Respuesta :

We can conclude that the value of both mean and median increases when we remove the lowest value, 0, from the data set.

What do we mean by mean and median?

  • The mean is the average of a set of values in mathematics and statistics. The mean can be calculated in a variety of ways, including the simple arithmetic mean (add the numbers and divide the total by the number of observations), geometric mean, and harmonic mean.
  • The median is the number in the middle of a sorted list of numbers, and it is more descriptive of the data set than the average.
  • When there are outliers in the sequence that could skew the average of the values, the median is sometimes used instead of the mean.

(1) First, we have to find the value of the mean and median with the value of 0.

(A) Mean: Sum of all values/Number of terms

  • = 700/10
  • = 70

(B) Median: If the number is an even number, add the two middles and divide by 2.

  • = 75 + 80/2
  • = 155/2
  • = 77.5

(2) Now, we have to find the value of the mean and median without the value of 0.

(A) Mean: Sum of all values/Number of terms

  • = 700/9
  • = 77.77

(B) Median: If there are an odd number of observations, the number in the middle of the list is the median.

  • = 5th term from both sides is the middle value
  • = 80

Therefore, we can say that the value of both mean and median increases when we remove the lowest value, 0, from the data set.
