WALT:

compare and describe the variation between theoretical and experimental distributions in situations that involve elements of chance.

My next step is to continue to apply my knowledge of statistics and probability in a variety of real world situations and contexts.

Find fractions, decimals, and percentages of amounts expressed as whole numbers, simple fractions, and decimals.

problem and explanation:
W.A.LT : find fractions, decimals and percentages of amounts expressed as whole numbers,simple fractions and decimals.
68 is 37.40 the first jeans are cheaper by 3.80.

The second tracksuit is cheaper because 25% 64 is 48 and 30% of 86 is 60.2.The second track suit is cheaper by 22.20.

The first sweat shirt is cheaper than the second because 30% of 60 is 42 and 40% off 72$ is 43.20 the first sweat shirt is cheaper than 1.20 the second one.


the first jacket 30% off 120 is 84  and the second one is 76.80 so this one is cheaper.

I figured all of these out  by first turning the percent into a fraction then timing it by the cost and dividing by the fractions denominator.then misusing the from the total cost.

The least you could spend would be 200.40 and the most would be 224.80 you could save 24.40

Rich Assessment Task: WALT:  Use side or edge lengths to find the perimeters and areas of rectangles, parallelograms, and triangles and the volumes of cuboids.

1. 6 by 6 [all around]
Because first I drew the different tables that made 36 and found the smallest one which was 6 by 6.
2. 6 by 8
I used the same strategy as the first one but for 48 which was 6 by 8. 3. 3 bags. I went 20 times 30 = 600 and we have bags that will cover 200 square meter so if you go 200 times 3 =600.So the answer is 3 bags.

mean midian mode and range Evidince

we had to get 90% here is my evidence from ixl.
I was doing MEAN.MEDIAN.MODE AND RANGE.

I can read and interpret a range of graphs

For maths I have been learning to read and interpret a range of graphs. This relates to the National Standards as it meets the criteria of: Delete the ones that are not yours

• I can identify patterns and trends in context, within and between data sets (Year ⅚ standard)
• I can compare distributions visually (Year ⅞ Standard)
• I can compare sample distributions visually, using measures of centre, spread, and proportion (Year 9/10)

Here is link to my Statistical Literacy spreadsheet yes no maths statistics  which shows all of the graphs and tables I can read and interpret.

I have also compared and contrasted some of the graphs. Below are the links to them

• Example 1 Compare and Contrast map
• Example 2 compare and contrast map

My next step is to use these in my leadership investigation next term.
