**Common Questions About the TDIST Formula:**

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?**

1. The TDIST formula is used to calculate the probability of a student or person in a series of students or persons with a particular t-score or value.

2. It can be used to calculate the range of scores for which the occurrence of an individual score is statistically significant.

**How Can the TDIST Formula be Commonly Mistyped?**

1. The formula is often written as “T-DIS” or “TDIST.”

2. The parameters are sometimes confused: the two that are most often mistaken are degrees of freedom (df) and the percentile (p).

**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.
