\[\quad \begin{array}{ccccc} \hline \frac{\textrm{class limits}}{\textrm{lowerupper}} & \frac{\textrm{class boundary}}{\textrm{lowerupper}} & \frac{\textrm{class}}{\textrm{midpoint}} &\text{tally}&\text{frequency}&\frac{\text{cumulative}}{\text{frequency}}\\ \hline 1 & & \\ \hline & & 4&6 \\ \hline & 5 & 4\\ \hline & & \\ \hline & 1 & \\ \hline & 1& 2\\ \hline \end{array}\] this is not the actual table. I'm new to making tables with Latex. Those numbers are just place holders so that my table doesn't collapse...now to my questions...

I found the class width to be 6 \[\frac{430}{8}=5.375\] 34 21 37 31 10 24 39 10 17 18 32 17 3 10 6 5 6 6 13 22 25 3 5 2 9 3 0 4 29 26 5 5 24 15 3 8 16 9 10 3 12 10 10 10 11 12 13 1 9 43 13 14 32 24 15

for the first column... so would I write 06 612 1224 how do I know where to start the class limits? I know that I should add six to the upper and lower limit to get to the next limits, but where do i start?

Well, one thing is you don't want the classes to overlap, so maybe 06, 713, 1420, etc.

It looks like discrete data, so you don't have to worry about continuity corrections.

but I have to add 6 to the lower limit and to the upper limit. If I do what you did that would be adding 7 to each 06 713 Would that mean it doesn't matter where I start? could I do... 05 611 1217 ?

Yeah, I think since 0 is included in the data, 05, 611, .. would be better if you want to have 8 classes. It'll overshoot a little at the end, but will include all the data.

Why would it overshoot at the end?

8 classes with a width of 6 each would go to 47 (481 because starting count at 0)

It's fine though, otherwise if you only had a width of 5, it would only go to 39 and that is less than your maximum value.
