What is the correct sequence of operations for calculating the mean and standard deviation on a calculator?

To calculate the mean and standard deviation using a calculator effectively, it’s essential to follow a specific sequence of commands tailored for statistical analysis. The correct sequence starts by setting the calculator in the appropriate mode for statistical computations. This typically involves selecting a statistical mode, often found under a button labeled 'MODE', before moving to the 'STAT' function where data input and calculation processes are initiated.

Following the selection of the statistical setting, entering the data points is usually done through a specified command (in this context, indicated by '1 0'), which allows for the input of raw data. After entering the data, commands such as 'RCL, 4' and 'RCL, 6' are relevant as they retrieve the calculated values for the mean and standard deviation from the calculator’s memory.

In this case, the sequence provided emphasizes first ensuring that the calculator is in the correct statistical mode, which is crucial because it optimizes the calculator to perform the necessary statistical functions. This approach allows users to handle data effectively and retrieve essential statistical measures without confusion.
