One week in October in Iqaluit, Nunavut, the daily high temperatures were -4.6°C, -0.5°C, 1.2°C, 2.3°C, -1.1°C, 1.5°C, -3.0°C. What was the mean daily high temperatures for that week?
Well first, you have to know what a mean is. A mean is the sum of all the data, divided by the the number of data. Also known as the average.
1) Well, the first step is to group together the positive and the negative numbers.
2) Then add the like signs together.
3) Add the sums together.
4) Divide the sum of the data by the number of data (in this case, 7)
1) (-4.6, -0.5, -1.1, -3.0) + (+1.2, +2.3, +1.5)
2) = -9.2 + 5
3) = -4.2/7
4) = -0.6

Great Job Kristin!But there might have been too much colour? because it is kind of confusing when you show how to do the actual question.
Hey Kristin! Great job in explaining the steps. I agree, there may be a bit too much colour. So just keep in mind that the colour is there to make important terms stand out. Also, you might want to fix the extra spacing. Great work, Kristin!
Awesome post Kristin!^^. I liked how you explained what the mean was. You explained to us so clearing on what you have to do to get the answer.I also liked how you made the numbers lager to get our attention.
Hello Kristin! I like what you did with the question, with the words... anyways, great use of colour and I like how you explained what the mean was before getting started on the question. Good job (:
