Find the Average Without Calculating: Numbers 133, 106, 176, 126, 199

Question

Without calculating, choose the average of the following group of numbers:

133,106,176,126,199 133,106,176,126,199

Video Solution

Step-by-Step Solution

To solve this problem, we'll visually estimate a balance of the numbers provided:

  1. First, identifying the extremities: - The lowest number is 106 106 - The highest number is 199 199 .
  2. The middle range involves 126 126 , 133 133 , and 176 176 , which cluster around 148 148 .
  3. Although 199 199 and 106 106 stretch the average, 133 133 and 126 126 counteract 176 176 's high point.
  4. Thus, balancing these extremities by approximating allows 148 148 to emerge as a logical middle value.
  5. Therefore, the estimated average that best represents the centrality of these numbers is 148 148 .

Accordingly, we choose 148 as the best estimate for the average, which is represented by Choice 3: 148 148 .

Answer

148
