Step 1:Calculate the test statistic value (x) using the following formula, Test statistic = (x̄ -μ) / (s/√n) We can write the above formula in the Excel format as follows: =(B9–B10) / (B11/SQRT(6)) Enter the above formula in cellB12and press“Enter”.As a result, Excel...
The standard error of the mean is a key statistic in understanding sampling distributions. In this article, we’ll show you how to calculate it in Excel using a simple formula that incorporates the standard deviation and sample size. Calculate standard error of the mean in Excel ...
Answer to: In Excel, how do I calculate the sample mean of the costs when I have expenses in one column and the number of days spent in another...
a. Calculate the test statistic (and for Excel users, the p -value) when x = 145 , s = 50 , and n = 100. Use a 5% significance level. H 0 : = 150 H 1 : < 150 b. Repeat part (a) with x = 140. c. Repeat part (...
The Excel CORREL Function returns the correlation coefficient (Pearson’sr) of two data ranges. What is the Correlation Coefficient? The correlation coefficient, usually referred to as Pearson’sr(named after Karl Pearson, the person who developed it), is a statistic that tells you how strongly ...
Chi Square Test in SPSS. Chi Square P-Value in Excel. A chi-square statistic is one way to show a relationship between two categorical variables. In statistics, there are two types of variables: numerical (countable) variables and non-numerical (categorical) variables. The chi-squared statistic...
Now you can use this along with the "Tdist" function to find the P-value. In another empty cell, type "=TDIST([t statistic], [degrees of freedom], [number of tails])" to perform the relevant significance test in Excel. Again, the square brackets are where you enter your specific dat...
