Lengths of 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 centimetres
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 of this table is 230.  

Median of this 200.

Mode of this table is 192.

Range of this table is 297.

I think most of the chains have a different measurement because of how the students made them.  The shortest chain was Ben and Dion having a measurement of 86 centimetres and I think it was short because they cut the strips into big strips.  The longest chain was Viliami and Howard’s measuring 383 centimetres.  To make it that long, they had to cut the strip into thin strips.  The difference is that if you cut the strips bigger, your chain will get smaller but if you cut the strips into thin strips, your chain will get longer.

Studyladder

This site is called Studyladder.  This is a site that everyone knows about because most of the school homework and school work is put on Studyladder.  In this problem, I have to figure out the length of each piece of wire made from the square.  The answer to this one is 9 cm.  I figured this out because 4 x 9 = 36.  Each length of wire is 9 cm.  Studyladder is a fun site to play on.  I would like to play more games like this on this site.
