What does it mean when data sets overlap?
@RonakShah by “overlap” I mean the pourcentage of data that is present in both datasets, taking under account that 0 means no data. For example, for column 201603 , the data in rows 1 and 3 are present in both datasets, so they overlap. –
Which word best describes the degree of overlap between the two data sets?
When looking at the data sets, notice that the only overlap in the middle, by a few points. There is overlap, so it isn’t “none” it isn’t much so it wouldn’t be “high” or “moderate”. It would be considered low overlap. So the answer is none.
What does it mean when the confidence intervals overlap?
If those intervals overlap, they conclude that the difference between groups is not statistically significant. If there is no overlap, the difference is significant.
Which word best describes the degree of overlap between the two data sets low moderate high?
How to calculate the significance of an overlap?
Calculate the significance of the overlap of two groups of genes drawn from the set of genes in the genome. Number of genes in set 1. Number of genes in set 2. Overlap between set 1 and set 2. Number of genes in the genome. (For the Kim lab full genome microarray, 17611 is the number of good spots.)
How to calculate the significance of two groups of genes?
Enter two lists of genes, or files containing list of genes, and indicate what comparison should be perfomed. Calculate the significance of the overlap of two groups of genes drawn from the set of genes in the genome. Number of genes in set 1.
How to measure similarity or dissimilarity between two?
I performed a Z test comparing the two correlation coefficients obtained from the 2 sets of data. However, this only concludes that the linearity of the two data sets are extremely similar (Z score of the difference in coefficients only 0.080083.
How can I compare groups with unequal sample sizes?
I have two datasets containing Z-score data. However both of them are of highly different sizes, i.e one has 500 samples while the other has 4. I want to determine if the differences between the samples is statistically significant.
