  • Thank you so much for your videos! They make it much easier to understand statistics! 1 suggestion though, most of the problems I have end up with decimals & I am never sure where to round off, maybe you can show some examples with numbers like that? Thanks again!

  • @AmyOneal1523 I will include some examples of rounding -- thanks for the suggestion. This is also a great question for your professor. Where does he/she want you to round. In my classes the whole number if fine because statistics is all about estimating anyway.
