Stats sharp shooting
Statistics
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 to lOOK 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 the total 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).
My numbers are 1,18,7
The mean is 8
The median is 7 because it is the number in the middle
I have no mode
The range is 17
Zara 0,12,25=37
Georgia 4,14,18=36
Thomas 1,15,25=41
Jett 13,15,25=53
Jacob 30,25,23=78
37+26+36+41+53+78=271
The mean is 15
The mediam is15
The mode is 25
The range is 30

Camp Goals
My goal is to : Eat the food that I am given
I have chosen this goal because: I am really fussy and I will get hungry if i don't have any food.
I know I have achieved this: When i'm not hungry and I have ate every thing on my plate.
I can help myself achieve this by: Trying just a bit of everything.
My goal is to: Not talk to people while we are getting told instructions.
I have chosen this goal because: I do that all the time and don't know what to do.
I know I have achieved this: when I am confident to go first.
I can help myself achieve this by: Not standing by people I will talk to.
