Solution 12272: Computing One-Variable Statistics Using the TI-34.
How do I compute one-variable statistics using the TI-34?
The following example will demonstrate how to compute one-variable statistics using the TI-34.
Example: Find the sum, mean, population standard deviation, and sample standard deviation for the data set: {45, 55, 55, 55, 60, 80}.
• Press [MODE] [5] to enter the statistics mode.
• Input 45, then press [Sigma +] to save the point.
• Input 55, then [Sigma +].
• Input 55, then [Sigma +].
• Input 55, then [Sigma +].
• Input 60, then [Sigma +].
• Input 80, then [Sigma +].
• Press the [2nd] key, then [1] to calculate the sum.
The answer is 350.
• Press the [2nd] key, then [4] to calculate the mean.
The answer is 58.33333333.
• Press the [2nd] key, then [6] to calculate the population standard deviation (n weighting).
The answer is 10.67187373.
• Press the [2nd] key, then [5] to calculate the sample standard deviation (n - 1 weighting).
The answer is 11.69045194.
Please see the TI-34 guidebook for additional information.
