# Ti-83/84 Calculator Tutorial

These tutorials were created using TI-Smart View, a Texas Instrument product. You will have to allow pop-ups and have the latest Flash version installed to access the tutorials.

- finding mean, median, mode: will help you find mean, median and mode on the calculator (Ch 3 section 1)
- standard deviation/variance: learn how to put data in your calculator and find the sample standard deviation and sample variance (Ch 3 section 2)
- calculating the mean and standard deviation for grouped data: how to calculate the mean and standard deviation for grouped data (Ch 3 section 3)
- five number summary/boxplots: help in finding 5 number summaries on the calculator and constructing boxplots on the calculator (Ch3 sec 5)
- scatterplots tutorial: an example of a scatterplot entered on the TI84 caluclator. You may need to click on the "pop up blocker " at the top of your screen when this tries to open. These tutorials do have audio (Ch 4)
- calculate r on the calculator: learn to calculate r and r squared on your calculator (Ch 4 sec 1)
- view entire problem with paired data:
- input data in lists
- create scatter diagram
- calculate the least squares regression line (also graph it and find predicted value)
- calculate the correlation coefficient
- calculate the coefficient of determination

- finding sum of residuals squared: helps you with homework and quizzes. I will not ask you to calculate this on a test (Ch 4 sec 2)
- combinations and permutations: how to enter combinations and permutations on the calculator (Ch 5 sec 5, you will see this notation in Ch 6)
- probability distribution: a prob. distribution (it says frequency in the video, this is an error); shows you how to find mean, expected value, standard deviation and variance. (Ch 6 sec 1)
- binomial distributions: use this to put the binomials in the calculator (Ch 6 sec 2)
- standard normal distribution: how to enter Standard Normal Distributions in the calculator (Ch 7 sec 2)
- normal probability distribution: information for entering normal distributions in the calculator (Ch 7 sec 3)
- finding confidence intervals sigma known: find confidence intervals when the population standard deviation is known.
- Z Interval (Ch 9 sec 1)
- confidence intervals sigma unknown: find confidence intervals when the population standard deviation is not known
- T Interval (Ch 9 sec 2)
- confidence intervals about pop. proportions: create confidence intervals about a population proportion (Ch 9 sec 3)
- hypothesis tests for a population mean, sigma known: find the Z Test statistic and p-value (Ch 10 sec 2).
- find t test statistic, sigma unknown: the calculator steps that you will use when sigma is known and you want to conduct a hypothesis test or find the p-value (Ch 10 sec 3)
- To find z test statistic for population proportions
- This should help you find the z test statistic when testing a hypothesis for a population proportion. It also computes the p-value (Ch 10 sec 4)

- hypothesis test and conf intervals for dependent samples: how to enter the data, find the differences, then compute the test statistic, p-values, d-bar and standard deviation of the differences. You will also see how to find a confidence interval for the differences of dependent samples (Ch 11 sec 1)
- inference on two means independent samples: how to enter data in the calculator and find the test statistic, p-value, and compute the confidence interval of independent samples (Ch 11 sec 2)
- inference about 2 pop proportions: how to enter in your calculator the information to find test statistics for 2 population proportions. You will also see how the calculator finds p-hat. You will see how to compute the Confidence interval for the differences between 2 pop proportions (Ch 11 sec 3)
- matrices and contingency tables: you will be able to find expected values, test chi square values and enter matrices (Ch 12).
