Entering One-Variable Data 1. Press ()to clear existing statistical data. 2. Key in each x-value and press . 3. The display shows n, the number of statistical data values now accumulated. Pressing actually enters two variables into the statistics registers because the value already in the Y-register is accumulated as the y-value. For this reason, the calculator will perform linear regression and show you values based on y even when you have entered only x-data - or even if you have entered an unequal number of x-and y-values. No error occurs, but the results are obviously not meaningful. To recall a value to the display immediately after it has been entered, press . Entering Two-Variable Data If the data is a pair of variables, enter first the dependent variable (the 2nd variable of the pair) and press , and then enter the independent variable (the first variable of the pair) and press . 1. Press to clear existing statistical data. 2. Key in the y-value first and press . 3. Key in the corresponding x-value and press . 4. The display shows n, the number of statistical data pairs you have accumulated. 5. Continue entering x, y-pairs. n is updated with each entry. To recall an x-value to the display immediately after it has been entered, press . Correcting Errors in Data Entry If you make a mistake when entering statistical data, delete the incorrect data and add the correct data. Even if only one value of an x, y-pair is incorrect, you must delete and reenter both values. 12-2 Statistical Operations
