• What can Represent Data?
• At Sal said you can record data on a bar graph so that's one way you can represent data.
• At Sal refers to the graph as a bar graph, sometimes known as a histogram. Do they mean the exact same thing or are there differences?
• one more difference between bar graph and histogram is space between bars.. if there is space between bars then it is bar graph, if there is no space then it is histogram. width of bar on histogram depends on interval on x-axis. u can also put smooth curve on values of histogram i.e., known as density

• how do you do stem and leaf plots
• The Stem acts like the tens place and the Leaf is the ones place so you take one number from the stem and one number from the leaf. Than you do that goin down a level after you complete one leaf.

• at how did he get 160-80=20 and somehow said below 100? I need help with this question and I am currently going to 6th grade in September so please help me.
• Sal tells you he is doing Max - Min.
The max value = 100, not 160. So, the calculation is 100-80 = 20.

Sal's writing is just a little sloppy, so one of the zeroes looks a little like a 6.
