Need some help from anyone thats any good with maths/statistics. Or does a science based thing and can remember what this test is on about =).

Got some data..

.174 10.000
.019 15.000
.296 20.000
.248 25.000
.457 30.000
.405 35.000
.014 40.000

Need to run that and two other sets of data like that through an ANOVA test to basically say their is a significant difference between the value and 30 from that of 20, 25 etc.

Got this program called SPSS and not sure how to put the data in to get what I want out of it. Don't have to use the program that program if excel or whatever can do it.

Anyone any idea? Cheers!
 
One-Way ANOVA

Independent

Procedure
• Analyse, compare means, one-way ANOVA
• Move the dependant variable into dependent list
• Move independent variable into factor
• Click on ‘Options’, ‘Descriptive’, and ‘Homogeneity of variances ’test then ‘Means plot’
• Click on ‘Post hoc’, then ‘Bonferroni’

Interpretation
Descriptives show the average mean
H of V, Sig. should not be significant, P should be greater than 0.05

---------------------

Guess who had a SPSS exam last week! :eek:

Done all that but I must be doing something wrong; what am I looking at to say you can see that the value at 30 has had a significat increase that the value at 20? Getting nothing in the Sig column.

should have probably kept the stuff I written the other year about how to do these tests =/
 
Sure you're ticking all the boxes? I don't actually have SPSS so you've got the best i have! :(
I confess i'm still trying to understand the basics..i know the procedures and roughly the figures i am looking for but what specifically the figures mean? I'm stuck..hopefully someone can shed some light. :)
 
Are you a psychology student as well Jon? :p

edit: I guess you haven't got the book called "Descriptive Statistics Using SPSS" then... perhaps one of your mates has it?

Biology here; I seem to be doing more maths and english atm tho :rolleyes:

ANOVA
Sum of Squares df Mean Square F Sig.
VAR00001 Between Groups .181 6 .030 . .
Within Groups .000 0 .
Total .181 6
VAR00002 Between Groups .101 6 .017 . .
Within Groups .000 0 .
Total .101 6
VAR00003 Between Groups .161 6 .027 . .
Within Groups .000 0 .
Total .161 6

Thats the table I've come up with no idea what I'm actualy looking for to get what I want from that.

I could use a regression analysis but then I'm in the same boat as now =(

Edit: I dont think anyone I know will have that book we barely use SPSS. Ive got graphs, Q10 values allsorts that proves what I was testing just my tutor has "suggested" I use one of these tests.

Well, I know you are a Psychology student given the chat we had in the penultimate "all nighter thread" a while back. :p What a coincidence you are called Jon too.
 
"ANOVA test compares 2 or more groups whereas a T-test is for no more than 2"

Does this mean that a group is a set of data, like above or is a group just the mean?
