office.com/myaccount - A t-test, a type inferential statistic, is used to determine whether there is a significant difference in the means of two groups. This may be due to certain features. It is used when data sets are normal and have unknown variances. For example, the 100-times coin flip data set. The t-test can be used to test an assumption that is applicable to a population. The t test can be used to determine if there is any significant difference between the before and after results or if they could have been due to chance. A drug manufacturer might use the t test to determine if a new drug is effective. This is used to determine if the means are different. The greater the difference between the two samples, the higher the t-value.
Excel Statistical functions include the T-TEST Function. It will calculate the probability associated with a Student’s T-Test. This function is often used to determine the probability of two samples with the same mean. Excel's T-Test function calculates the probability of significant differences between two data sets, regardless of whether they are both under the same population with the identical mean. T-Test also checks whether the data set we use for calculation is one-tail or two-tail with a type of variance that could be equal or different. www.office.com/setup
