How to find standard deviation on calculator TI-84?
Understand the Problem
The question is asking how to use a TI-84 calculator to find the standard deviation of a dataset. This involves inputting data into the calculator and using specific functions to compute standard deviation, either for a sample or a population.
Answer
The standard deviation is displayed next to 'Sx' (sample) or 'σx' (population).
The standard deviation can be found next to 'Sx' for sample standard deviation or 'σx' for population standard deviation.
Answer for screen readers
The standard deviation can be found next to 'Sx' for sample standard deviation or 'σx' for population standard deviation.
More Information
The TI-84 calculator can distinguish between sample standard deviation (Sx) and population standard deviation (σx). It is important to select the correct one based on your data set.
Tips
A common mistake is confusing the sample standard deviation 'Sx' with the population standard deviation 'σx'. Ensure you are selecting the correct one for your type of data.
