Find the mean median range and mode for 3, 3, 4, 8, 9, 10, and 12

Answer 1

Hey there!

‘‘Find the mean median range and mode for 3, 3, 4, 8, 9, 10, and 12’’

• Mean is known as your AVERAGE number. You have to ADD all of your NUMBERS the DIVIDE it by the TOTAL numbers in your given set

• We have the total of SEVEN numbers in your set

“3 + 3 + 4 + 8 + 9 + 10 + 12 / 7”

6 + 4 + 8 + 9 + 10 + 12/7

10 + 8 + 9 + 10 + 12/7

18 + 9 + 10 + 12/7

27 + 10 + 12/

37 + 12/7

49/7 = 7

Answer: Mean = 7 ✔️

• Median is the number you see in the center (the middle) of the problem. You can solve for this by putting your numbers from least to greatest

• If you have an ODD number in your given set then your middle number will be the single number)

• If you have an EVEN number then you have to average your TWO middle number

“ 3, 3, 4, 8, 9, 10, 12”

• you still have 3 on both sides of your 8 (3 is an ODD number, so we have to let it be be a single number)

Answer: mean = 8 ✔️

• Mode is your number than you see repeated OR more than once

• We “3” repeated so it is your Mode

Answer: Mode = 3 ✔️

Answers ⬇️

• Mean: 7 ☑️

• Median: 8 ☑️

• Mode: 3 ☑️

Good luck on your assignment and enjoy your day!

Answer 2

Answer:

Mean: 7

Median: 8

Range: 9

Mode: 3

Step-by-step explanation:

First, to find the mean of a set of numbers you need to add up all of the numbers and divide that by the total amount of numbers. In this case that makes this equation, $\frac{3+3+4+8+9+10+12}{7}$, which is $\frac{49}{7}$, which is 7.

To find a median you need to find the middle number. A handy trick I use for this is to place my fingers on the first and last number, and then move them towards the middle, at the same time by one number until there is just one number left in the middle. If there are no numbers left after doing this, meaning there are an even amount of numbers given, the median is the mean of the last two numbers that were covered. In this case, this is not necessary, so the median is 8.

The range is the difference between the maximum and minimum of a data set. In this case that would give you the equation Range=12-3, which means the range is 9.

Finally, the mode is the number that occurs the most in a given data set. In this case the number that occurs the most is 3, which occurs twice compared to every other number which only occurs once.
