Filling in Anova Tables

I'm sorry I couldn't copy the actual box separation lines.

The following table is the output from an ANOVA analysis comparing 4 groups. There were a total of 160 subjects. Use this information to fill in the question marks in the output table. In the event the data shifts after I save this comment, I need to see the df for between and within, SS for between, MS for Within and the F statistic.
I would greatly appreciate any assistance.

Thank You

df Sum Sq Mean Sq F p
Between ? ? 13.786 ? <0.001
Within ? 137.47 ?
Total 159 ?

Would like to figure out formula of nonlinear (curving) line based on X,Y values displayed so that I could create a graph, place new scores on that line based on only having X, not Y. So formula would need to be Y = ? Plug in new X values and get new Y values. Have researched quadratic regression formulas since they look most like graph in article, but so far no joy. My statistical analysis skills are limited.
Here's the article PDF which includes the graph (Figure 1):https://www.google.com/url?url=http:...ruTHvQ&cad=rja

Would appreciate any suggestions on how to derive a formula from the data points given in the graph that can be used to get Y when a new X (score) is known.

Thank you.

Best Wishes,

Tue, 18 Jul 2017 13:51:49 GMTI'm trying to work out whether there are relationships between two IVs and one DV (I'm not interested in correlations between IVs, though they may overlap so).
I have no categorical data, and data for my DV and one IV meets parametric assumptions.
I was thinking that a multiple regression would be appropriate, but I am very unsure. Or could I just a simple correlation?

I'd appreciate any suggestions as I have tried to wrap my head around conditions for each test but am very confused!
