how do i assess for normality in the data? spirometry/anova/friedman test how is a friedman test used how do i determine if clot time is normal clot testing definition and example can i use a randomised test for hypercoagulability are the friedman test normal if a test is normal how many clots should you have how to determine if a variable is normal can anova be used in a repeating measures study how long should i take a friedman's test after clots what tests are normal? what is the difference between a friedman test and a coagulability test what test is used to measure coagulability how many test for coagulability clot time_postop vs clot time_ 1mo what test should i use for hypercoagulability before surgery which is a repeatable test for coagulability how many hypercoagulability testing is normal which test uses Friedman's nonparametric method? is clot testing normal
