Funny Youtube Cumulative Frequency Graphs Using Class Data

I designed this lesson for my Year 10 class, with inspiration from my lecturer (@solvemymaths).

The initial example is using simply collected data - how long they spend getting ready each morning (not including eating their breakfast).

The main task is to watch a short youtube video of 7 animals with funny voiceovers (BBC's Walk on the Wild Side). They rate each animal's sketch out of 10, and then you take in the results. The link is in the notebook, and below:

Get the pupils to find their total rating over all 7 clips, and use the data to complete the Rating overall cumulative frequency table and graph as an example.
Next take in all the scores (show of hands) for each clip and complete the table on slide 3. The task for the rest of the lesson is for all pupils to draw cumulative frequency tables and graphs for each clip. Leave a space next to them, so they can do the box plots of each graph next lesson.
