I am trying to find out how reliable my data is with these tests. Choosing the Correct Statistical Test in SAS, Stata, SPSS and R. The following table shows general guidelines for choosing a statistical analysis. Excuse my ignorance. I'm not an expert of non normal distributions. Like a z-test, a t-test also assumes a normal distribution of the sample. Proper Statistical Test for Binary Data. You can use Mc Nemar Test or two paired proportion (Z test) test for binary data. A t-test is used when the population parameters (mean and standard deviation) are not known. But most importantly, statistical analysis is part of the grade, but I dont know much beyond Mean, median, mode and SD. What statistical test could i use with such binary data for my dependent variable? Often, you want to show that a new test is similar to another test, in which case you use an equivalence test. Cite 27th Oct, 2013 comparing summary measures of diagnostic accuracy such as sensitivity or specificity using a statistical test. An independent samples t-test is used when you want to compare the means of a normally distributed interval dependent variable for two independent groups. If the test statistic is lower than the critical value, accept the hypothesis or else reject the hypothesis. 2 The development of the χ 2 test is fairly intuitive. you can use Cochran Q test. t-test groups = female(0 1) /variables = write. We emphasize that these are general guidelines and should not be construed as hard and fast rules. Generally, 2 main tests are used for comparing categorical data across ≥2 groups: χ 2 test 1 (sometimes referred to as Pearson’s χ 2 test of independence) and Fisher’s exact test. I think what you are looking for is to test if different groups are independent of each other, in other words if the severity of group affects having or not having a particular interaction. For example, using the hsb2 data file, say we wish to test whether the mean for write is the same for males and females. Or, you may wish to show that a new diagnostic test is not inferior to the existing test, so you use a noninferiority test. Is there a statistical (R based) test to do this? T-test. if your categorical data have binary and paired groups are 3 or more. A t-test is used to compare the mean of two given samples. Usually your data could be analyzed in multiple ways, each of which could yield legitimate answers. This isn't binary data, your doing statistics over proportions. If you have rating data then reducing it to binary will probably lose information unless the rating data are very sparse. Ask Question Asked 6 years, 1 month ago. Just looking for help.
