question on ANOVA?

Question

0 个投票

I have some data for 6 different age groups looking at the population change from 1994 -2014.

When doing the ANOVA analysis would I be comparing the means of the different age groups or for the different years?

I know this is more theory than MATLAB related.but would really appreciate any help.

Thanks

I believe the ANOVA would be more appropriate than Chi-squared for your data. It’s going to be a challenge in any event, considering you’re comparing six different age groups from two separate regions. I would begin by learning everything I could about the ANOVA to understand how best to apply the ANOVA to your data.

ok.

I have looked into the ANOVA. i understand how it works. BUT i was just unsure on whether it would be applied to the age groups or to the different years.

I have done it to the age groups. But now have doubts. It was a clear result to show that the null hypothesis is rejected. This made me consider again whether it should have been applied to the years.

Also the ANOVA would not get applied to the 2 different tables of values for the different regions at the same time. I would apply anova to the first table in my first region then apply it to the second region. (RESULTING in two differnt anova tables)

I am doing this correctly aren't i?

‘When doing the ANOVA analysis would I be comparing the means of the different age groups or for the different years?’

Both,as well as the two regions. I’ve not dealt with ANOVA in several years. There are designs that would allow you to determine the significance of all of these.
