Dear all,
I hope you are keeping well.
I used calculated z scores to compare the differences between groups of different normal distributions. My scores are both positive and negative (please see the attached image).
I was asked to find a reputable source of a Z score table with at least +2/-2 range of values to obtain the statistical significance values and include it as a supplementary material for a publication but I am struggling to find one that will satisfy them.
Could anyone help supply a table?
Many thanks

Thank you for your answers. The second link provided by Jochen Wilhelm will probably be the best option for me to use.
Many thanks!
Type
cbind(seq(-3,3,.01),pnorm(seq(-3,3,.01)))
in R or similar commands in most good stats software. If you want things like 2-tailed values you can calculate these from the second column.
You may get the table from Specially prepared for Behavioural and Biological Researcher called: Statistics Table and you could also get the table from Standard Statistics Textbook as Appendix at the back of textbook.
Look for Statistics Tables for mathematicians, engineers, economists and the behavioural and management sciences by H. R. Neave
The table at

is interactive and easy to use
