The Response Table for SIgnal-to-Noise Ratios contains a row for the average signal-to-noise ratio for each factor level, Delta, and Rank. The table contains a column for each factor.

The Response Table for Standard Deviations contains a row for the average signal-to-noise ratio for each factor level, Delta, and Rank. The table contains a column for each factor.

- Delta
- Delta is the difference between the maximum and minimum average response (signal-to-noise ratio or standard deviation) for the factor.
- Rank
- The Rank is the rank of each Delta, where Rank 1 is the largest Delta.

To get the standard deviation for each factor level, consider the following example. You have a Taguchi design where the inner array has 2 factors (A and B), stored in C1 and C2, respectively, and the outer array has two responses, stored in C3 and C4.

- Choose .
- Choose Mean.
- In Input
variables, enter
`C3 C4`. - In Store result
in, enter
`C6`. - Click OK.

- Choose .
- Choose Standard deviation.
- In Input
variables, enter
`C3 C4`. - In Store result
in, enter
`C7`. - Click OK.

- Choose .
- In Store
result in variable, enter
`C8`. - In Expression, enter:
`10 * LOGT(C6**2 / C7**2)`. - Click OK.

You can also get these signal-to-noise ratios by choosing , clicking Storage, checking Signal to Noise ratios, and clicking OK twice.

- Choose .
- In Variables, enter
`C8`. - In By variables
(optional), enter
`C1`. - Click Statistics.
- Check Mean.
- Click OK twice.

The last column in the worksheet (named Mean1 if there was not already a column with this name before performing these steps) contains the signal-to-noise ratios that are displayed in the Response Table for factor A.

Repeat Part 4, entering `C2` in step 3 to get the signal-to-noise ratios for factor B.
