can u help me here's the problem:

predict the number of computer science degrees to be awarded in 2000:

YEAR NUMBER OF DEGREES
1976 47
1980 124
1984 385
1988 748
1992 1533
1996 2588

heres what I got so far,

124-47= 77
385-124= 261
748-385= 363
1533-748= 785
2588-1533= 1055

thanks for your help!

Are you supposed to be finding the regression equation? Or using some other method for finding a model?

What are you supposed to do with this list of differences?

Please reply with clarification, including the methodology you're supposed to be using, and your reasoning for the steps you've done so far.

Thank you.

well I'm trying to find a pattern so I can predict what number of degrees they will hand out in 2000 the reason it did the steps i did is because i was trying to see if a number was somehow being added to the previous number each time forming a pattern i can use to further predict the outcome of number of degrees in 2000.

Yes, but what method are you supposed to use? What method(s) did they cover in class? Are you supposed to be using your graphing calculator to find a regression equation? Or something else?

The year-to-year changes are not the same amount each time. This is not a strictly linear relation.

But it could be approximated by a linear model... or a quadratic, cubic, quartic,... and so forth. What sort of model are you supposed to find? What do the instructions for the exercise say?

Thank you.

it doesn't give me a specific mathamatic prcedure to use. all it says is:
Predict the number of computer science degrees to be awarded in 2000. Show the mathematics you used and explain how you arrived at your prediction.

thanks,

And no particular method was covered recently in class...? Then what method(s) do you know? Maybe we can help you work through one of them.

Thank you.
