Statistics

What: In Room 24 this week we have
been learning how to work out mean, median, mode and range.
So what: A lot of us didn't know
how to work these out so we started from scratch. To learn how to work out
mean, median, mode and range we watched a video. He showed us an example of his
one and how he did it then gave us a problem and by then a lot of us had worked
it out by now.
Now what: Next week we are
learning about statistics investigations. I don’t know what that is and maybe
some other people don’t so I’m excited about learning something new.

Some of the statements we made were:
"There were more people in the 1.56-1.60m range than the others." Mackenzie
"Most people in the classroom are shorter than Miss Biggs." Shae
"The range is 35cm." Jared S
"The mode is 1.40-1.45 and 1.66-.1.70." Jakob
Mean, median or mode - which is which and how do you remember? Looks like you have been carrying out some hands-on activities to help you. I recall sharing this video with my Year 7&8 class last year (Jared, you might remember this one).
