## Where is the FCDF on TI-84?

The F distribution is a probability distribution that is an asymmetric distribution used to analyze certain types of hypothesis tests. . Scroll down to options #9 and #0 on this menu to find Fpdf and Fcdf.

**What is FCDF?**

Fcdf( is the F-distribution cumulative density function. If some random variable follows this distribution, you can use this command to find the probability that this variable will fall in the interval you supply. The arguments lower and upper express the interval you’re interested in.

### How do you calculate chi squared?

Let us look at the step-by-step approach to calculate the chi-square value:

- Step 1: Subtract each expected frequency from the related observed frequency.
- Step 2: Square each value obtained in step 1, i.e. (O-E)2.
- Step 3: Divide all the values obtained in step 2 by the related expected frequencies i.e. (O-E)2/E.

**How do you calculate chi-square?**

Step 2: Perform a Chi-Square Test of Independence. Press stat and scroll over to TESTS. Then scroll down to X2-Test and Press Enter. For Observed, choose the matrix you entered the data in.

#### How do you calculate p-value?

The p-value is calculated using the sampling distribution of the test statistic under the null hypothesis, the sample data, and the type of test being done (lower-tailed test, upper-tailed test, or two-sided test). The p-value for: a lower-tailed test is specified by: p-value = P(TS ts | H 0 is true) = cdf(ts)

**What is the p-value for t test?**

T-Values and P-values A p-value from a t test is the probability that the results from your sample data occurred by chance. P-values are from 0% to 100% and are usually written as a decimal (for example, a p value of 5% is 0.05). Low p-values indicate your data did not occur by chance.
