Answer 1

An important question here is "what would a 'correct' frequency table look like? What would an 'incorrect' one look like?

What's your take on the given frequency table? Does it look OK or not? Why?

Answer 2

Answer 4

I typically help others by asking pertinent questions. The ones I've asked you are fair questions, since you do need to be able to recognize at least a valid frequency table.

Answer 5

Please note:

34 21 54 44 33 17 22 56 78 62
48 25 39 64 70 65 52 43 21 22
46 28 39 76 63 39 42 55 29 30

is not a frequency table. it's just a list of data. You yourself need to organize this data in a frequency table. I thought you'd posted a frequency table earlier, but now I don't see it.

Answer 6

I did it's still there.

Answer 7

Here is another one. http://static.k12.com/calms_media/media/1422500_1423000/1422839/1/bd734e9e9c67aa2f044be432f557561fca6bb8ab/MS_PA_131004_171520.jpg

Answer 9

Thanks anyway @mathmale .

Answer 10

My suggestion is that you take the data:

34 21 54 44 33 17 22 56 78 62
48 25 39 64 70 65 52 43 21 22
46 28 39 76 63 39 42 55 29 30

and make up your own frequency table. Compare your table to the one you've posted. If the two tables are the same, then the given frequency table is fine; if different, then it's possible that the given frequency table is wrong. Please try this.

Have you made up a frequency table before? It's well worth the practice.

Answer 11

Great. Start now and make up your own freq. table; we'll then compare yours with the given one.
