Hi, I'm Jimmy Chang, and we're here to talk about the criteria for rounding the figures in statistics. Now, the criteria really depends frankly on a couple of things. One important factor is on significant digits. Okay. Now, this is going to vary from study to study and actually is use a lot in science. Now, significant digits can be either measured, okay, or exact. I think by now, you'll have already gone over exactly what the difference between the two is. So, significant digits is going to be a, of important criteria for that. Now, the other thing to consider would be how many significant figures are involve. Now, if you've taken science courses or even statistics, another way to say it would be sig. figs because you can have four sig. figs, five sig. figs or you know, depending on what the study is, it could be less or even more than that. But, the bottom line here is that in terms of the criteria for rounding, we're looking at significant digits as well as the number how many significant figures or sig. figs that you want to round to and it'll give you an idea as to what the criteria is going to be. So, I'm Jimmy Chang, and that gives you a glimpse as to the criteria for rounding figures in statistics.
