Accelerated students: Answer the above and make a line plot of the data.

Answer 1

Mean: 88.5

Median:90

Mode:98

Explanation:

For mean, what you need to do is add all of those numbers up and divide them by how many you have. So once you add up all those numbers, divide them by six because there are 6 numbers. For the median, order the numbers from smallest to biggest and cross off every one until you get left with the number in the middle. If there is an even number of numbers and there are two middle ones, add them together and divide them by 2. For mode, it’s the one with the most. Please don’t hesitate to write back if you need anything else or any of the answers are incorrect. Have an amazing day!!

Answer 2

76 82 87 93 95 98

Mean -
76+82+87+93+95+98 = 531
531/6 = 88.5

Range -
98 - 76 = 22

Median -
Because there are 6 numbers you have to find the average of the middle two
87+93 = 180
180/2 = 90

Mode -
No number is repeated so there is no mode.
