Rhino Registered User regular http://jwilson.coe.uga.edu/emt668/emt668.folders.f97/weber/gpc/ti83m.htm July 2011 edited July 2011 in Help / Advice Forum Any easy way to calculate E on the ti-84? I can do it manually, but it's a lot of button mashing. I would assume/hope there is just a simple function that I can punch in a few values and have it do it for me. I've never used APPS, is there a downloadable (free and legal) program that would do https://forums.penny-arcade.com/discussion/145327/margin-or-error-on-the-ti-84 this?

Registered User regular July 2011 There is no dedicated button for calculating a margin of error. You can certainly run whatever confidence interval you are attempting, subtract your upper bound from your lower bound and divide by two.

Registered User regular July 2011 Calculating a CI is a program on the TI84; one would hope writting down the two numbers and then performing basic arithmetic wouldn't be a strain or button mashing.

For example, suppose we wanted to know the percentage of how to adults that exercise daily. We could devise a sample design to ensure that our sample estimate will not differ from the true population value by more than, say, 5 percent (the margin of error) 90 percent of the time (the confidence level). How to Compute the Margin of Error The margin of error can be defined by either of the following equations. Margin of error how to find = Critical value x Standard deviation of the statistic Margin of error = Critical value x Standard error of the statistic If you know the standard deviation of the statistic, use the first equation to compute the margin of error. Otherwise, use the second equation. Previously, we described how to compute the standard deviation and standard error. How to Find the Critical Value The critical value is a factor used to compute the margin of error. This section describes how to find the critical value, when the sampling distribution of the statistic is normal or nearly normal. The central limit theorem states that the sampling distribution of a statistic will be nearly normal, if the sample size is large enough. As a rough guide, many statisticians say that a sample size of 30 is large enough when the population distribution is bell-shaped. But if the original population is badly skewed, has multiple peaks, and/or has outliers, researchers like the sample size to be even larger. When the sampling distribution is nearly normal, the critical value can be expressed as a t score or as a z score. When the sample size is sm
