Question

For the following scores, find the mean, median, and the mode.

2,2,0,5,1,4,1,3,0,0,1,4,4,0,1,4,3,4,2,1

Answer 1

---*okay lets first find our mean step by step*---

step 1. We have to take our numbers and add them all toegther
2+2+0+5+1+4+1+3+0+0+1+4+4+0+1+4+3+4+2+1= 42

step 2. Now count how may numbers we have.
there are 20 numbers.

step 3. Now divide the outcome (42) by the number of numbers (20)
42 ÷ 20 = 2.1

So..
mean = 2.1

---*Now lets find our median. (step by step)*---

step 1. Put all your numbers in order from least to greatest.
0, 0, 0, 0, 1, 1, 1, 1, 1, 2, 2, 2, 3, 3, 4, 4, 4, 4, 4, 5

step 2. Find the number that is in the very middle, since there is no middle number but instead there are two 2's. We take them and find the mean of those 2 numbers.

step 3. Finding the mean of the middle numbers.
2 + 2 = 4
Now divide
4 ÷ 2 = 2

So..
median = 2

---*Now lets find the mode of this set.*---

we do this by finding the number that occurs the most in the data set.

step 1. We know that both 1 and 4 occurs 5 times.
So the answer is both of them :)
mode = 1 and 4


So to sum every thing up, your answers are..
Mean = 2.1
median = 2
mode= 1 and 4

Good Luck! :)

Answer 2

The answer is median= rearrange in ascending order thats is... 0,0,0,0,1,1,1,1,1,2,2,2,3,3,4,4,4,4,4,5, so the median is =2 Mode= biggest number= 5 and smallest number = 0 Mean= sum of observations divided by no.of observations= 0+0+0+0+1+1+1+1+1+2+2+2+3+3+4+4+4+4+4+5 divided by 20 = 42 divided by 20 = 2.1 is the answer. Hope this helps you !! :p
