Prob>ChiSq<br />

Prob Other option to select a confidence level, <strong>and</strong> select one-sided or two-sided<br />

confidence intervals. You can also type a known sigma. If you use a known sigma, the confidence interval for<br />

the mean is based on z-values rather than t-values.<br />

The Confidence Intervals report shows the mean <strong>and</strong> st<strong>and</strong>ard deviation parameter estimates with upper<br />

<strong>and</strong> lower confidence limits for 1 - α.<br />

Save Comm<strong>and</strong>s for Continuous Variables<br />

Use the Save menu comm<strong>and</strong>s to save information about continuous variables. Each Save comm<strong>and</strong><br />

generates a new column in the current data table. The new column is named by appending the variable<br />

name (denoted in the following definitions) to the Save comm<strong>and</strong> name. See Table 2.12.<br />

Select the Save comm<strong>and</strong>s repeatedly to save the same information multiple times under different<br />

circumstances, such as before <strong>and</strong> after combining histogram bars. If you use a Save comm<strong>and</strong> multiple<br />

times, the column name is numbered (name1, name2, <strong>and</strong> so on) to ensure unique column names.<br />
