    Probability of overlapping criteria

    What is the best statistical method to measure the probability of people fitting a certain criteria in my data overlapping with another criteria? I am tasked to display this in a column/bar chart for a simple display of the consequence of its selection on other relevant pots of data.

    Comparing two groups and then the sub-groups (of the same)

    Hi I have four groups of variables A, B, C and D. The variables A and B also have (natural) sub-groups (say A1, A2, A3 and B1, B2 and B3). I want to compare them as follows: A - B - C - D (using ANOVA for 4 groups) A1 - B1 (using t test for two samples) A2 - B2 (using t test for two samples)...

    Error bars don't overlap but aren't significantly diff. - interpretations/reasons?

    Hello all, I'm struggling to understand/interpret my graph and kruskal wallis test. Basically, I've created a bar graph which looks pretty good. There are 5 bars, each with error bars, and none of the error bars overlap. All of my 5 groups look significantly different. HOWEVER, when I do a...

    Overlapping sample: t test with partial pairing??

    Hi - I've a work project that requires a stat test between Product A and Produce B performance ratings (On a scale of 1 to 5 how well did Product A / B perform?) We are treating the data as interval scaled. The samples partially overlap. e.g. Product A has n=500; Product B has n=500...

    Looking for significance when taking overlap into account

    I am currently working on completing my dissertation. I am looking for a way to test for distinct but overlapping phases. I have run ANOVA's and used Games-Howell Post Hoc's to determine which phases show significant differences in their means. But, since the variable being used to compare means...

    Address whether one overlap is significantly bigger that of another related overlap

    I could really use a hit as to which statistical test I need to use to address the following problem: I have three different species: A, B and C. I have compared the quantitative overlap (i.e. something that was measured and counted in all 3 species) of Species A and B, respectively, with...
