Hello Dr. Sandahl Nelson,
I hope you are very well.
I am a student who is extremely weak in math. In order to be very strong in math, specially for engineering field, could you provide me with sequential order of mathematical topics and textbooks. With what should I begin so that I can master big topics like calculus, statistics, probability ... etc.
Your guidance is precious to me.
Thank you so much.

Are these things all we need to know to get 4 or 5 points in Ap exam if we take AP stats by ourselves?

If you are creating a histogram using a computer (or calculator) you will have labels for each (equally spaced) bar (eg, 0- <10, 10 - <20, etc. ) this way you clarify where exactly the values go.
If you are drawing a histogram wit put the data edge point in the bar that makes the groups even.
For example, if your lines were at 0,10, 20, 30, etc. then the first group is 0-9.99999, the next group would be 10 - 19.999999.
I hope this helps.

hey! in a histogram, if you have a data point that is equivalent to the "edge points," do they contribute to the left bucket or the right bucket of the histogram?
