Mr Ogilvie's Maths | Statistical Investigation

 Mr Ogilvie's maths groups were focusing on measuring the length of an activity and converting times into median, mean and mode. 

With a range of numbers, median is the middle number. The mean is adding all the numbers and dividing the total by how many numbers there were originally. The mode is the number that appears the mose.

The statistical investigation was about investigating how long it would take to do an activity 5 times. Once we measured the time, we converted the each time into mean. 

Then, we converted the overall times into median and mode.

We answered the question "What could have made it faster or slower?" and converted the times into seconds, minutes and hours. We then found out the combined time spent, and the elapsed time.

LI: to investigate the units of time.
