Stats Sharp Shooting

WALT calculate the mean, median, mode and range for a set of data.

TASK Elly and Troy want to find out once and for all:

  • which Activity Group has the overall best score, (mean)
  • which Activity Group has the highest middle number, (median)
  • what score was the most common, (mode)
  • which activity group has the highest range. (range)  

In everyday life people collect data to look for trends and make decisions. In order to analyse the information, we need to understand the different ways tolOOK at the data.

Success Criteria you will know you are successful when:

  • calculate the mean by adding up all the data (9 + 4 + 4 + 5 + 8 = 30) then divide thetotal by how many numbers there were (9, 4, 4, 5, 8 = 5 numbers so 30 ÷ 5 = 6).
  • calculate the median by ordering all numbers from smallest to biggest then selecting the middle number (4, 4, 5, 8, 9 = 5 is the middle number). If there are 6 numbers e.g. 4, 4, 5, 6, 8, 9, then the median is halfway = 5.5.
  • calculate the mode by identifying which number occurs most often (4, 4, 5, 8, 9 = 4 because there are two of them). You can have more than one mode.
  • calculate the range by finding the difference between the highest and lowest numbers (9 - 4 = 5).

Data: 4,14,18
The mean is: 12 ( 4+14+18= 36 divided by 3=12)
I have no Mode
The Range is: 14
The median is: 14

Group J

Georgia: 4,14,18 

Zara: 0,12,25

Maia: 1,18,7

Jacob: 30,25,23

Jett: 13,15,25

Thomas: 1,15,25

36+37+26+78+53+41= 271

Mean: 15
Median: 15
Range: 30

Reflection: I think our group worked great as a team and we all shared our scores kindly. I got it on my blog quick and I think it looks pretty cool.

Statistics:  Stem and Leaf Graph

WALT: gather, display and discuss data

Success Criteria:  

  • Gather relevant information

  • Display data on a stem and leaf graph

  • Make some conclusions about the data


To present information about reaction times using a ruler.

Data: 19,12,19,14,3,22,7,9,1,30+ 

Stem and Leaf Graph:

Sorted Stem and Leaf Graph:


My best score was 1 and my worst score was 30+ because I did not catch it.

The mean was 12.4. I added it up and divided It by how much data there was. There ten dat so I divided it by 10


Self Assessment: I think I acheived all of these below because I went threw & checked.

  • I can gather relevant information

  • I can display data on a stem and leaf graph

  • I can make some conclusions about the data  

Peer Assessment:Katelyn: yes yes yes you acheived all of the stuff below. Good job Georgia 

  • I can gather relevant information  

  • I can display data on a stem and leaf graph 

  • I can make some conclusions about the data

Measles Spread In Aukland

Nearly 40 people in Auckland have recently been diagnosed with the infectious measles disease.
Westlake Boys High School on Aucklands North Shore is one of the hardest hit communities with 20 ill students.
Several other Westlake Boys High pupils who have not been immunised against measles have been asked to stay away for the next two weeks.
Measles is a very serious disease that is highly contagious and can spread through the air when an infected person coughs or sneezes.
The symptoms include fever, a cough, sore eyes and a rash. There is no treatment, and complications can be severe.
The Auckland Health Service has estimated that around 750 people are at immediate risk of catching the highly contagious disease.
Dr. Julia Peters said the Health Service had been working with the North Shore school for just over a week when the first case of measles was found there.
"This is definitely more than what we'd normally see. We're working hard to contain the measles within the Auckland region."
Dr. Peters said many people who had come down with the disease had recently been overseas and, in particular, in the Philippines.
The public health service has sent information to parents and students at Westlake Boys High and asked that those students who are not sure whether they have been immunised against measles to stay away.
"What we're trying to do is isolate those students as well as those who have measles, because students who are not immunised can get sick," she said.
Another seven cases of measles in Auckland are being investigated - three of them from the same school.
What to watch for Symptoms
* High fever.
* Runny nose, cough, red eyes.
* Small white spots inside mouth.
* Red, blotchy rash on face and neck and later over entire body.

WALT: Analysing an article
Task: Answer questions based on a Newspaper Article.
Success Criteria:
  • Show critical thinking in your answers.
  • Answer questions in full sentences.
  • Use correct spelling and punctuation.

1) How do people contract measles?
Other people that have caught it might cough or sneeze on you and measles are contagious so you will catch it.

2) Why do you think so many students at Westlake High School have contracted measles?
Maybe someone that goes to that school went to the Philippines and the could have caught it from there.

3) What is the Auckland Health Services main role in this measles outbreak?
To make sure that no one else catches the measles because measles in the old days would kill you. They also have to make sure all the caregivers know about the measles.

4) In the article Dr. Peters said “many people who had come down with the disease had recently been overseas and, in particular, in the Philippines.” Why do you think this is?
Not long ago there was a big wave and a lot of people died and got sick. Maybe that's why???

5) In your opinion what would be the best way to avoid getting measles?
Getting The injection because then you body will be stronger than the measles, You body will get rid of measles.

Use the following criteria to assess yourself and your peer
  • Show critical thinking in your answers.
  • Answer questions in full sentences.
  • Use correct spelling and punctuation.

Self Assessment: I think I could spend a little more time thinking about it because I could describe it more.
