natima [27]

Answer:

  • <em>Mode is 0</em>
  • <em>Median is 1 </em>
  • <em>Mean is 2.625</em>

Step-by-step explanation:

  • <em>To find the mode, or modal value, it is best to put the numbers in order. A number that appears most often is the mode.</em>
  • <em>0, 0, 0, 1, 2, 4, 7, 7 = mode is 0</em>

<em></em>

  • <em>To find the Median, place the numbers in value order and find the middle number.</em>
  • <em>0 , 0 , 0 , 1 , 2 , 4 , 7 , 7 = median is 1</em>

<em></em>

  • <em>The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are.</em>
  • <em>0 + 0 + 0 + 1 + 2 + 4 + 7 + 7 / 8 = mean is 2.625</em>
