It shows how to scale frequencies that sum to 80 into a target total of 40,000 by halving, and how to calculate midpoints for a grouped frequency table for a frequency polygon. It then covers Venn diagram probability, including that with 10 numbers and three in set B, P(B) is 3 out of 10 and P(not B) is 7 out of 10. Finally, it demonstrates mean calculations for stick lengths, where five sticks have mean 4.2, changing the result if one stick length is 7 cm versus 17 cm."}
