Fig 2.The model has two springs and a weight in the center. In our model, the string is made of two springs, with a mass in the center. Let’s try it on the guitar. Re-tune the high E string to its former pitch. (It should be the same pitch as the next string, when the n...
ValueMeaning TXFS_TRANSACTED_VERSION_NONTRANSACTED 0xFFFFFFFE The file is not a transacted file. TXFS_TRANSACTED_VERSION_UNCOMMITTED 0xFFFFFFFF The file has been opened as a transacted writer. If the handle has been opened as a transacted reader, the value returned for this member is a...
While the above is quite simple to read, it is quite slow (as you will see soon) and worse – it does not ‘inline’ meaning you cannot use the above inside a inline table-valued function. This last property was very important for us, because in the case we were looking at, the ab...
In conversation, one of our former colleagues has even expressed the opinion that “all interesting scientific questions in psychology can be broken down into two groups and a t test”. These t tests are almost always conducted within the framework of frequentist statistics, with a p value as ...
If sample sizes are large the t-test is fairly robust to departures from normality, meaning that you don’t always have to stick to the assumption of normality if your sample size is large. Independence (for Independent Samples T-Test): Observations in one group should not be related to ...
In linear regression, thet-statistic is useful for making inferences about the regression coefficients. The hypothesis test on coefficientitests the null hypothesis that it is equal to zero – meaning the corresponding term is not significant – versus the alternate hypothesis that the coefficient is...
the tests were anonymous so I can’t match up each individual student’s pre- and post- test. About 100 students took the pre-test and only 65 completed the post-test. They answered 20 different questions on the topic. What’s the best way to approach the stats to determine whether the...
format_is) f(0) sum stats(chi2) format_bs and format_is are two binary variables (coded 0 or 1). I have two questions: 1 - I have added 'format-is' after 'count' because, without a variable name, it did not work. But I don't understand the meaning of ...
“biased” by the test. In the initial version of the IAT’s scoring algorithm, there was even a correlation between cognitive-processing speed and IAT score,the researchers Sam G. McFarland and Zachary Crouch found: Those who were a bit cognitively slower got higher IAT scores, meaning they...
