This statistic is preferable to the F statistic when the assumption of equal variances does not hold. Welch. In the One-Way ANOVA dialog box, click Options.
ANOVA and F-tests assess the amount of variability between the group means in the context of the variation within groups to determine whether the mean differences are statistically significant. While statistically significant ANOVA results indicate that not all means are equal, it doesn’t identify which particular differences between pairs of means are significant.
1. This is a pretty small sample size per group and such a small sample is not necessarily recommended. It is certainly legitimate to do an ANOVA with this size Repeated measures anova with spss 1. Presented by Dr.J.P.Verma MSc (Statistics), PhD, MA(Psychology), Masters(Computer Application) Professor(Statistics) Director, Centre for Advanced Studies Lakshmibai National Institute of Physical Education, Gwalior, India (Deemed University) Email: vermajprakash@gmail.com This Presentation is based on the book titled Repeated Measures Designs … 2015-08-03 Det SPSS gör är att räkna ut ett så kallat F-värde.
An F-value is the ratio of two estimates of the variance, an estimate derived from the variance BETWEEN GROUPS is the numerator and an estimate derived from the variance WITHIN GROUPS. An F-value of 1 means that you get the variance between groups that you would expect given the variance in the population – so, an F of 1 is what you would expect by chance. After a simple ANOVA, I found the df to be: F(2, 58) = 18.084. Afterwards, I needed to analyse the three groups in a general linear model with the groups as the fixed factor and one extra random factor. My SPSS output showed the following: (F(2, 4.048) = 57.678).

F-statistics (41,2)= 10.61893 , p.v <0.05 (0.000192<0.05). So , we conclude that there is significant statistical relationship b/w CP ,CO2 and PD because p.v of F-statistics is less than 0.05
You are looking at whether you have more variation between your groups instead of within your groups. An F-value is the ratio of two estimates of the variance, an estimate derived from the variance BETWEEN GROUPS is the numerator and an estimate derived from the variance WITHIN GROUPS. An F-value of 1 means that you get the variance between groups that you would expect given the variance in the population – so, an F of 1 is what you would expect by chance.
