Scatter Graph

Walt: write a blog post about scatter graphs.

I created 3 different sized paper planes out of newspaper. I got into a group of 3 and we all threw each of our planes. We had to throw each plane 4 times and then measure from where we stood to where the plane had landed in cm. Then I recorded the measurements onto a table. On graph paper we plotted our measurements. After that we drew a straight line to connect as many points as we could.

Length Of Chains

Length Of Chains

Walt: Arrange length in order.

        Find mean, median, mode and range.

         Explain the differences in length.

Pairs	Length of Chain in centimetres
Ben and Dion	86
Wesley and Koliata	169
Lorenzo and Liam	170
Ifa and Tane	192
Shanelle and Alyssa	192
Andrea and Lana	200
Ketura and Serena	220
Stephanie and Cherish	286
Petuana and Yazmin	304
Munokoa and Samuel	320
Viliami and Howard	383

Mean = 229.272727273 cm

Rounded Off = 229.3 cm

Median = 200 cm

Mode = 192 cm

Range = 297 cm

The reasons why the shortest chain is 86 cm and the longest chain is 383 cm is because they measured their individual chain to either be thick or thin, which would make it short or long. Also they might have used the length side which would create longer chains or they used the width side which would have made smaller chains.

How do you think NZ did well in the Commonwealth Games

In 2014's Commonwealth Games, England won 174 medals which made them win the Commonwealth Games. New Zealand won 45 medals. But when you divide New Zealand’s population with the 45 medals New Zealand comes on top of the leader board. When you divide England's population with 174 medals it puts them in 7th place. So if an event happens in NZ, the best place will be Dunedin because they have the fewest people living there. I think that New Zealand did exceptionally well.
