I’m an instant gratification kind of girl. I want results, and now please, ok? When I submitted my chapter 1 homework for my statistics class online last night, I was excited to see it graded within two hours. (I was even more excited to see the comments from the instructor on the assignment saying “Outsanding! Perfect score!” Kudos to my husband, the tutor.) I’ve got chapter 2 due on Friday, and we’re stuck on the last question, so I posted a question to the profession on the online discussion board for the class last night. She still hasn’t answered it, and none of the other 25 students have chimed in either. The assignment is due tomorrow night, and I’d rather not be working on homework at that point, considering I’m done except for this single question.
(I have to create my own data sets - 2 of them in fact - and then put one on a regular frequency table and the other on a grouped frequency table. The twist is that she stated to use a max of 10 scores, and grouped frequency is best used, per the book, on 15 or more scores. I don’t get it. Anyway…)
And my other class…there’s no gratification there, instant or otherwise. I submitted a paper online Sunday (the due date) and haven’t heard a thing back yet. I’d like to know if I’m on the right track BEFORE I start my outline for my research paper.
I’m also bent because the statistics teacher has got chapter 3 work due on Monday, but the forms and questions to submit said work won’t be available until tonight. I guess that’s her way of saying enjoy a few hours of statistics this weekend? I could be done with it if I had the questions to turn in!

I don’t remember anything about a minimum number of scores needed for grouped frequency, so consider that might just be the author’s bias. What’s more important is that the sample size relative to the population is statistically significant. If the population is 20, a sample of 10 is statistically significant. If the population is 1,000,000, a sample of 1,0000 might not be considered statistically significant.
But, I might be wrong.
Look at the big brain on Tim!
I finally figured it out - if the possible values of X are more than 15 or 20, you want grouped frequency. So if the possible scores on a test ranged from 0 - 20, grouped frequency it is.
congrats on the perfect and outstanding grade
