Paired t-test虽然在2nd-level analysis中,但是由于本次实验每个被试只有一张图(自己内部已经没有东西可以比较了),所以可以直接在2nd-level analysis中做检验。 P.S. 如何判定需不需要做1st-level analysis呢?简单地说,就是每个被试只有一张图的时候不需要再做1st-level analysis。 >Specfy 2nd-level >选目录,d...
我看这个意思就是想让你做再现性实验，用配对t检验的方式证明方法的可靠性

From the results of this transform, click Analyze and choose to do a t test. On the t test dialog, choose a paired t test. Notice that you are chaining the transform analysis with the t test analysis. Manually compute the antilog of the means of the differences. This is the geometric ...

In such situations,paired t-testcan be used to compare the mean weights before and after treatment. Paired t-test analysis is performed as follow: Calculate the difference (dd) between each pair of value Compute the mean (mm) and the standard deviation (ss) ofdd ...
A paired t-test is a form of hypothesis testing where the subject is held constant and an analysis is done for two different conditions. This would be useful in comparing whether two machines are different by having the same operator do the test. ...
We calculate a test statistic. Our test statistic is 0.750. We find the value from the t-distribution. Most statistics books have look-up tables for the distribution. You can also find tables online. The most likely situation is that you will use software for your analysis and will not use...

They demonstrate a valid application of the paired t-test in their analysis. First, the paired t-test is applicable when measuring how a static group of subjects perform in two conditions, and this requirement is met. Second, the paired t-test is appropriate when the independent variable is ...
