(meh) Make the bars touch!
DON’T!
LET YOUR Y – AXIS START AT SOMETHING OTHER THAN ZERO!!! (why? Let’s take a look!)

19. Anything wrong with this graph?

20. Always start this axis at zero!!!

Ignore the Margin Of ERROR!!!
Huh?

27. Please find this report online!!!

28. Any issues with the data?
If you’re interested:

29. Let’s check the rest of those MOE’s…

30. Now let’s USE those MOEs…

33. Let’s do an in – class quiz!
Margins of Error (MOEs) must be added (and subtracted) to/from any sample statistic to help alleviate sampling error.
