Mean Icicles

Hope everyone is well.

Anyone bored, please see my post from yesterday.

Here’s another one for you. We’ve been learning about mean, median and mode in mathematics. Yesterday, I spotted these beauties hanging from a gutter: icicles! I carefully counted and measured them using technology (it was too cold and dangerous otherwise) and found the following lengths:

{23cm, 40cm, 25cm, 28cm, 44cm, 25cm, 32cm, 34cm, 30cm, 28cm, 32cm, 49cm, 37cm, 25cm}

Find:

  1. the mean length of icicle in cm.
  2. the median icicle length, in cm.
  3. and find the mode.

We’ve also been working on the internal angles of polygons and so far have found out pentagons and hexagons. Find out more.

Alternatively, find three dice and have a game of Yahtze, or teach someone how to play it.

Hope everyone is well in these adverse conditions.

Best wishes,

Mr A
