We began math today in the textbook — a sample of fictitious student test data that ranged from a score of 54 to a score of 95. There were 25 pieces of data (i.e. 25 student scores in the set of data, ranging from 54 to 95).
We wondered why intervals ending in 60, 70, 80 were preferable to intervals ending in 59, 69, 79?
Is it because ending with multiples of 10 (e.g. 60, 70, 80) just seems more tidy and finished? What do you think?
We made observations about the graph in the example, which was made using the intervals 51-60, 61-70, 71-80, 81-90, 91-100.
Next, we used our observations to create Anchor Charts, one reference chart for the steps needed to create intervals out of a large set of numbers and one reference chart for the steps needed to create bar graphs using interval data.
