This tutorials were created using TI-Smart View, a Texas Instrument product.

You will have to allow pop-ups.

 

Finding Mean, Median, Mode

This will help you find Mean , Median, Mode on the calculator. (Ch 3 section 1)

Standard deviation/variance

Use this link to see 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

This is a video to show you how to calculate the mean and standard deviation for grouped data. (Ch 3 section3)

Five number summary/boxplots

Use this for help in finding 5 number summaries on the calculator and constructing boxplots on the calculator. (Ch3 sec 5)

Scatterplots Tutorial

You can view this video to see 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)

To calculate r on the calculator

Use this to calculate r and r squared on your calculator (Ch 4 sec 1)

View entire problem with paired data

1) Input data in lists, 2) Create scatterdiagram . 3)Calculate the least squares regression line,(also graph it and find predicted value) 4) calculate the correlation coefficient, 5)Calculate the coefficient of determination

Finding sum of residuals squared

This will help you with homework and quizzes. I will not ask you to calculate this on a test. (Ch 4 sec 2)

Combinations and Permutations

This will show you how to enter combinations and permutations on the calculator. (Ch 5 sec 5, you will see this notation in Ch 6)

Probability Distribution

This is a prob. distribution(I said frequency in the video--sorry). It will show you how to find mean, expected value, standard deviation and variance. (Ch 6 sec 1)

Binomial distributions

You can use this to put the binomials in the calculator (Ch 6 sec 2)

Standard normal distribution

Click here to see how to enter Standard Normal Distributions in the calculator. (Ch 7 sec 2)

Normal Probability Distributions

Click here to get information for entering Normal Distributions in the calculator. (Ch 7 sec 3)

Finding confidence intervals sigma known

This will help you find confidence intervals  when the population standard deviation is known.

Z Interval  (Ch 9 sec 1)

Confidence intervals sigma unknown

Use this to find confidence intervals when the population standard deviation is not known.

T Interval (Ch 9 sec 2)

Confidence Intervals about Pop. Proportions

This will help you create confidence intervals about a population proportion. (Ch 9 sec 3)

Hypothesis Tests for a Population Mean, Sigma known

Use this to find the Z Test statistic and p-value. (Ch 10 sec 2)

To Find t test statistic, sigma unknown

This is 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

Here you will find 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 confindence interval for the differences of dependent samples. (Ch 11 sec 1)

Inference on Two means Independent Samples

In this video, you will see 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

In this video, you will see 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)
