Choose Stat Proportion Stats One Sample With Data

Under the Values in: heading, click on the categorical variable with the outcomes for the test. Note: you may need to use the scroll bar for the white box to find the appropriate variable.

In the State: text-box specify the outcome that denotes a success. For example, if the outcomes are yes and no, and yes denotes a success, you would type yes in the text-box. WARNING: you must type the outcome exactly as it appears in the spreadsheet. For example if yes denotes a success and you type Yes with a capital Y, StatCrunch will not perform the test.

Under the Perform: heading, check the radio button for Hypothesis test for p. Complete the null hypothesis by entering the null value (type over the default of 0.5). To complete the alternative hypothesis, use the drop-down menu to select , , or .
