Find the mean, median, mode, and range of these numbers 75,95,90,95,60,95,75,95,90<br> Plzzzzzz
Shtirlitz [24]

Answer:

<em>Mean: 85 5/9</em>

<em>Median: 90</em>

<em>Mode: 95</em>

Step-by-step explanation:

<em>~ Part I ~</em>

1. To find the mean, let us take the average of the numbers through the addition of these values divided by the number of numbers:

75 + 95 + 90 + 95 + 60 + 95 + 75 + 95 + 90/9 = 770/9 =<em> 85 5/9 (85.55.....)</em>

<em>~ Part 2 ~</em>

1. Now let us arrange these numbers from least to greatest:

75 , 95 , 90 , 95 , 60 , 95 , 75 , 95 , 90 ⇒ 60,75 , 75 , 90 , 90 , 95, 95, 95,95

3. The median of this set would now be the middle number, which, (in this case) is ⇒<em> </em><em>90</em>

<em>~ Part 3 ~</em>

1. The mode is known to be the number repeated most often, and from the previous question we see the numbers arranged in a benficial manner. Now we can straight away see that the number repeated the most is ⇒<em> 95</em>
