You could return to your EXCEL spreadsheet and make this computation. If you do, you can verify that the pooled variance is 115.98, that the pooled estimate of the standard deviation is 3.4 and that the t-statistic - characterizing the difference between the two means in terms of multiples of the pooled estimate of the standard deviation - is 5.2.

How to Calculate Pooled Standard Deviations in Excel | Techwalla
Since 3.3062 < 4.462, fail to reject Ho and conclude equal variances so can use pooled standard deviation. Ho: μ1 – μ2 < 0. Ha: μ1 – μ2 > 0. df = 12 + 12 – 2 = 22. Using Excel’s average and stdev functions students can determine the sample mean and sample standard deviation of each of the samples. Sample 1: Sample 2:

Dec 13, 2013 · Based on adult studies, the common standard deviation was estimated at 8.1 pounds. The margin of error, standard deviation and confidence level are input into an Excel worksheet. The Z value is estimated using the NORMSINV function as shown in Figure 8.9. Figure 8.9 Data to Estimate Sample Size to Estimate (

Pooled methods are applied since the comparison of the largest to smallest sample standard deviation is ≤ 2 ----- 10.85 / 8.41 = 1.29 Again, we would have to first calculate these sample standard deviations so we would know whether to select in Minitab the "Assume Equal Variances".

In EXCEL, the function “stdev” uses the above formula for computing the sample standard deviation: For the steel thickness data, you would type =stdev(range) as shown below: This yields the value of s=4.492549. EXCEL does not automatically compute the standard deviation if the data is grouped. The computing formula to use in this case is ...

From the mean and standard deviation it is possible to model the distribution of masses as a Gaussian function, the well-known bell-shaped curve. The mean fixes the center (or top) of the curve, and the standard deviation determines the width of the curve—the distance between the inflection points on the curve is the twice the standard deviation.
