Significance Level Testing.And so to solve the p-value in an Excel spreadsheet, simply select a cell and type in t-dist( to bring up the formula and then type in the arguments, separating each by a comma Theres a significance calculator spreadsheet in Excel you can []Using a simple t-test, you can calculate a p-value and determine significance between two different groups of a dataset. If the result of a test — a t-test, for example — falls within a certain probability range, then the result is said to be significant.Excels TTEST function combines these two steps. It calculates the t- value internally and determines the probability. In this tutorial I will teach you about doing T tests in Excel 2013. T test is a statistical term which is used to find out a significance of the result and to check whether the resultFirst we will compare the alpha level (0.05) to the p-Value.
