Shanelle- Scatter Graphs

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.

Andrea- Estimation: Chains

Length of Chains

WALT: 1. Arrange length in order.

2. Find mean, median, mode, range.

3. Explain the differences in length.

Pairs	Length of Chain in centimeters
Ben and Dion	86
Wesley and Koliata	169
Lorenzo and Liam	170
Ifa and Tane	192
Alyssa and Shanelle	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 = 229.3  

Median = 200

Mode = 192

Range = 297

I think the lengths are different because of the strategy we used for cutting the paper. Some of them cut it from the length and others chose to cut from the width. Viliami and Howard probably made the longest chain because they took the time to measure and cut their strips evenly. Ben and Dion one was short because their strips of paper were big and used up most of the paper.
