Reading Graphs

W.A.L.T: To read different types of graphs

This is my maths presentation that I have finished off from wk 5. My group Tapaono and I have been learning about reading different types of graphs.

Finding the......

WALT: Identify trends and compare them between data sets.

This maths task for week 7/8. My group tapaono and I are learning about finding the mean median mode. Also to identify the mean median and mode in the data sets. I have completed the mths presentation and have answer the following questions.

Idea City

WALT - Synthesis ideas from different texts

This is my week 6/7 reading task. My learning intention is to synthesis ideas from different texts. The book that I am reading is called Idea City. This text is about a place in New Zealand named Christchurch that has recently had many earthquakes from the past years and all their stuff they were all gone. Luckily Christchurch has many people that has brilliant ideas. About how to bring back their beloved city.

My Speech

WALT - capture our audiences attention (Speech Intro)

Fidget spinners has been affecting the lives of children in schools. Kids from elementary and middle school have been dieing to buy one. Students are distracted from the fidget spinners, that’s why they have been getting lower grades and levels on their education. Teachers are not sure or have decided to ban fidget spinners in their classrooms or school.

Students in school have been bringing them to play in their classrooms and have not finished a single thing from their work on their netbooks or on paper and pencil. Some kids even hide it under their desks so their teachers won’t see them playing with it. In my opinion I agree that fidget spinners should be ban from schools. So that they can get back on track with their work.

In order to guarantee that we save students from these kind of toys and let them not be distracted. So my question to you is “should teachers ban fidget spinners”.

This is my writing for wk 6. Our learning intention is to capture our audiences attention. We had to make up our own speech and when we have edited it and we are happy with it. We post it on our blogs.

Mean, Median, Mode, Range

WALT: I will identify patterns and trends in context, within and between data sets; communicating findings, using data displays. Find the mean, median, mode and the range which is part of analysing data.

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

1. Find the mean in this set of numbers

3,7,8,4,2,6,5,4,3,9 - mean is 5.1

2. Find the mean in the set of numbers

4,12,5,6,11,9,5 - mean is 7.4

3. Find the mean in this tally chart

Pets owned by students	Number of students
Dogs	IIIII IIIII
Cats	IIIII IIIII II
Fish	IIII
Rabbits	II

The mean is 7

4. Find the mean in this set of numbers

24,12,16,18 17.5

5. Find the mean in this set of numbers

5,9,12,4,10,7 9.4

6. 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 3.3

Score	Frequency
1	4
2	3
5	8
Total	15

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

1. 10,14,17,12,19,11,16  14

2. 34,42,37,31,40  37

3. 101, 167,138,124,198,149  143.5

4. 54, 58,52,57,53,60 55.5

5. 1001, 1094, 1023, 1065, 1038, 1027, 1042  1038

6. Find the median within this tally chart

Pets owned by students	Number of students
Dogs	IIIII IIIII
Cats	IIIII II
Fish	IIII
Rabbits	IIIII III
Hamsters	II

Median is 8

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

1. 2, 1, 5, 3, 7, 8, 5, 3 ,9  appeared twice: 3 & 5
2. 1, 5, 3, 2, 9 ,4, 1, 6, 8, 0  appeared twice: 1
3. 23, 45, 78, 12, 45, 67, 32, 46, 93, 12 appeared twice: 45
4. 101, 121, 123, 145, 167, 121, 139, 145, 176 appeared twice: 121 & 145
5. 394, 273, 219, 294, 183, 291, 273, 288, 271 appeared twice: 273

Activity 4: find the range

1. 32, 41, 37, 34, 40
2. 100, 92, 96, 94, 98
3. 72, 79, 76, 74, 69, 80
4. 54, 57, 52, 55, 58
5. 112, 125, 115, 111, 120

Numerical order:

32, 34, 37, 40, 41 range: 9

92, 94, 96, 98, 100 range: 8

69, 72, 74, 76, 79, 80 range: 11

52, 54, 55, 57, 58 range: 6

111, 112, 115, 120, 125 range: 14

For this week, my maths group and I are learning about Mean, Median, Mode and Range. We had to complete this maths activity using our maths knowledge. For each activity we had to find the mean, median, mode and range. I hope I do more of these activities next time.

MY IKAN TEST RESULT

Today myself and my maths class have been doing an IKAN test. This is picture is the results from my IKAN test. I have some wrong and most right answers. We were lucky because we can do twice but the other time we did we had to do altogether as one class. But now we did it individuals. I am really happy for my results I have from my IKAN test.
