1. What is the TDIST formula?
2. What is the purpose of the TDIST formula?
3. How does one use the TDIST formula?

How Can the TDIST Formula be Used Appropriately?

What are some Common Ways the TDIST Formula is Used Inappropriately?
1. People may enter parameters that are outside the range of valid values.
2. People may also enter wrong values for the percentiles of the t-distribution.

What are some Common Pitfalls When Using the TDIST Formula?
1. Being familiar with the normal distribution is important; if the normal distribution parameters are used for the t-distribution, the results may be incorrect.
2. Make sure the parameters are within the valid range for the t-distribution.

What are Common Mistakes When Using the TDIST Formula?
1. People may miscalculate the degrees of freedom (df) or the percentile parameter.
2. People may also enter parameters that are out of the valid range for the t-distribution.

What are Common Misconceptions People Might Have with the TDIST Formula?
1. People may think that the t-distribution is equivalent to the normal distribution, which is not true.
2. People may also think that t-distribution is only applicable to one-tailed normal distributions, which is not the case.
