univariate question

[Angelz369]

I was wondering how you can predict something from a frequency table. For example, you are initially given data for 10 weeks and you have to put into a two-way frequency table where the independant variable is enrolment status and dependant variable is drinks alcohol. Then afterwards you are given extra data for another two weeks but then it says to predict whether the independant variable (eg. part-time employers) will drink alcohol (the extra data given doesn't say whether they drink alocohol or not).  So how do you predict in a word analysis if they will drink alochol for the overall thing.

Sorry if my wording is bad ^^"

To predict data, you need to do a regression analysis. Enter the data that you have values for both x and y for into your calculator. Then do a stat calculation, LinReg(a+bx). You now have the equation of a trend line, a prediction line. For the new values of that you have (let's say you have a value for Y but don't know what X is), substitute those into the formula for Y and see what result you get for X. You've now predicted what the X values will be, given those Y values.

Hope that makes sense!
