Answer:

The median is 30.

Step-by-step explanation:

To find the median, you must first list all numbers from least to greatest.

In this case, we get 20, 30, 30, 30, 60, 80, 90.

Median is the middle number in the group. Here, we can clearly see that 30 is the middle number.

Keep in mind that if a group doesn't have a middle number, a.k.a. even number of numbers, take the 2 middle numbers, add them, then divide the sum by 2 to get the median.

Answer:

you have an odd number, divide by 2 and round up to get the position of the median number.

Step-by-step explanation:

you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Answer:

Part A

  • C. 7.25

Part B

  • B. Ryan Shafer has been more consistent because his mean absolute deviation is less than Norm Duke’s.

Step-by-step explanation:

<u>Given data:</u>

  • 299, 281, 285, 269, 280, 269, 286, 287
<h3>Part A</h3>

<u>Find the mean of the data above:</u>

  • (299 + 281 + 285 + 269 + 280 + 269 + 286 + 287)/8 = 282

<u>Find absolute deviations, an absolute value of the difference of data and the mean:</u>

  • 299 - 282 = 17 ⇒ 17
  • 281 - 282 = -1 ⇒ 1
  • 285 - 282 = 3 ⇒ 3
  • 269 - 282 = -13 ⇒ 13
  • 280 - 282 = 2 ⇒ 2
  • 269 - 282 = -13 ⇒ 13
  • 286 - 282 = 4 ⇒ 4
  • 287 - 282 = 5  ⇒ 5

<u>Find mean absolute deviation:</u>

  • (17 + 1 + 3 + 13 + 2 + 13 + 4 + 5)/8 = 7.25

Correct choice is C

<h3>Part B</h3>

Less mean absolute deviation is the sign of more consistent data.

Since Ryan Shafer has smaller mean absolute deviation, he has been more consistent 7 < 7.25

Correct choice is B.
