For this weeks activity we got introduced to statistics but a few of us already knew what statistics was all about. I was working with a buddy who is Myztique and we figured out a lot of complicated equations of different kinds of graphs.

M.M.M  Mean, Mode, Median
Statistics name: Myztique and Anna
WALT Identify the mean, median and mode within a collection of data
Activity One
Answer the questions in a different colour
The definition of the mean in a statistical investigation is commonly referred to as the average. It is the total of all the data divided by the amount of data shown.
For example: if we have this range of data 3,5,7,1,2,3,6,8
3+5+7+1+2+3+6+5 = 32 = 4
8 8
 Find the mean in this set of numbers
3+7+8 +4+2+6+5+4+3+9 = 51 ➗ 10 = 5 r 1
Find the mean in the set of numbers
4+12+5+6+11+9+5 = 52 ➗ 7 = 7 r 3
 Find the mean in this tally chart

10 + 12 + 4 + 2 = 28 ➗ 4 = 7
 Find the mean in this set of numbers
24+12+16+18 = 70 ➗ 4 = 17 r 2
 Find the mean in this set of numbers
5+9+12+4+10+7= 47 ➗ 6 = 7 r 5
 CHALLENGE QUESTION: Find the mean within this data, use the frequency table to help you
1+5+5+2+1+2+5+5+5+5+1+2+1+5+5 = 50 ➗ 15 = 3 r 5

Activity Two
Answer the questions in a different colour
The definition of the median is the middle number within a set of numbers that have been put in order from size (biggest to smallest or smallest to biggest)
For example: 2,6,4,1,9 = 1,2,4,6,9 and the middle number is 4.
BUT say if there is more than one middle number… the median is found by taking the number midway between the middle pair of numbers:
3,6,1,4,9,2 = 1,2,3,4,6,9 → 3 + 4 = 3.5
2
Find the median in these sets of numbers
 10,14,17,12,19,11,16
10,11,12,14,16,17,19  the middle number is 14
 34,42,37,31,40
31, 34,37,40,42  the middle number is 37
 101, 167,138,124,198,149
101, 124, 138,149, 167, 198  the middle number is 143.5
 54, 58,52,57,53,60
53,53,54,57,58,60  the middle number is 55.5
 1001, 1094, 1023, 1065, 1038, 1027, 1042
1001, 1023, 1027, 1038, 1042, 1065, 1094  the middle number is 1038
 Find the median within this tally chart

2 ,4, 7, 8 , 10 = 7
Activity Three
The mode is the most frequent number in a set of data. The number that occurs most often.
For example: In a set of numbers 3, 7, 8, 4, 2, 6, 5, 4, 3, 9 there is two modes, 3 and 4 because they appear twice in the data set.
Note There can either be 0, 1 or 2 modes. If there are 3 or more numbers occur the same number of times, there is no mode.
Find the mode in these sets of numbers
 2, 1, 5, 3, 7, 8, 5, 3 ,9 = 3 and 5
 1, 5, 3, 2, 9 ,4, 1, 6, 8, 0 = 1
 23, 45, 78, 12, 45, 67, 32, 46, 93, 12 = 12 and 45
 101, 121, 123, 145, 167, 121, 139, 145, 176 = 121 and 145
 394, 273, 219, 294, 183, 291, 273, 288, 271 = 273

Multiplying Decimals
'
In this activity we are learning about multiplying whole numbers. For this presentation I had some help from my buddy Myztique. It was pretty tricky to do the word problems, but we just kept on going and did our work.

After that we had to make up our own hero and write about them I chose Jason Taumalolo and Adrienne wanted to do Michael Jones.
Conjunctions Complex Sentences
WALT: How to use conjunctions to construct complex sentences
In my literacy class we are learning about conjunctions complex sentences. We had to buddy up with someone so my partner was Adrienne first we were suppose to write about a book we were reading which was The Lion, the Witch and Wardrobe. Then we had to write sentences about Japan being a Zero Waste Town. If you want to find out more information please carry on looking through my presentation.
