Depending on the test you run, you may see other statistics that were used to calculate the P value, including the mean difference, t statistic, degrees of freedom, and standard error. The confidence interval and a review of your dataset is given as well on the results page. ...
In this chapter, we analyse the t -statistic for a linear model with one stochastic regressor and with autocorrelated errors under dynamic misspecification. The motivation for this is as follows. The t -test for a univariate regression model with one regressor is a special case of an omitted ...
One variable of interest: This is not correlation or regression, where you are interested in the relationship between multiple variables. With a t test, you can have different samples, but they are all measuring the same variable (e.g., height). ...

An additional concern with standard t tests is their sensitivity to outliers; a few extreme observations can exert a large impact on the value of the t-statistic and thereby have a disproportional effect on the resulting test. Several methods may be used to mitigate the impact of outliers (e...
Chimeric antigen receptor (CAR) T cell therapy has transformed the treatment of haematological malignancies such as acute lymphoblastic leukaemia, B cell lymphoma and multiple myeloma1–4, but the efficacy of CAR T cell therapy in solid tumours has been
The test statistic, ts, is calculated using a formula that has the difference between the means in the numerator; this makes ts get larger as the means get further apart. The denominator is the standard error of the difference in the means, which gets smaller as the sample variances ...
