Best ResponseYou've already chosen the best response.0well the idea is that class range is x_maxxmin divided by the number of classes.

Best ResponseYou've already chosen the best response.1bins are just ranges of xaxis, like to construct a histogram from a continuous variable you first need to split the data into intervals, called bins. so here your bins are 05.5, 5.511.5....... and u have 8 bins in total

JenniferSmart1

Best ResponseYou've already chosen the best response.1so my bins would be my class boundaries. I labeled the upper and lower bounds

JenniferSmart1

Best ResponseYou've already chosen the best response.1" if you want to separate grades based on a 10 point scale 60, 70, 80, 90, 100 would be the bins" So I guess I'm using a 5 point scale and my bins would be....0, 5.5, 11.5...no?

Best ResponseYou've already chosen the best response.1is a bin a range or a specific number? From the way they've written it's kinda confusing "if you want to separate grades based on a 10 point scale 60, 70, 80, 90, 100 would be the bins"

JenniferSmart1

hartnn

Best ResponseYou've already chosen the best response.1a bin is an interval : 1st bin: 05.5 2nd bin: 5.511 so bin is range
