# Stats lab (optional)

**About the labs**

The 1 credit stats lab is available for students who might move on to a 4-year college or university on a semester system to have enough credits to transfer. It is also available to students who want to have additional, structured activities to enhance their understanding of the concepts covered in the lecture class.

No additional concepts will be covered. Hands-on activities will be used reinforce the material. Spreadsheets will be used in each lab.

There will be 9 labs throughout the term. Each lab is worth 10 points. Your final grade for MTH298 with be the average of your lab grades.

Lab meets in Pendleton, Hermiston, and online every Friday at 10AM. Video conferencing links will be sent out each week.

**Lab 1**

For this first lab we'll use a modified version of section 1.5 in the book. Printable Version.

Further help and data are available at Coach Parker's Stats Blog.

**Lab 2**

For lab 2 we will explore data description. Check out the lab description and data: Lab 2.

**Lab 3**

For lab 3 we will explore discrete probability distributions and the relative frequency definition of probability, aka empirical or experimental probability.

**Lab 4**

This week we will explore continuous random variables and the normal distribution.

**Lab 6: Confidence Intervals, Means**

This week we will explore a confidence interval where the population standard deviation is unknown.

**Lab 7: Confidence Intervals, Proportions**

This week will explore confidence intervals on proportions using the data from last week on home prices in Pendleton.

**Lab 8 Hypothesis Tests, Meann**

This week we will explore a hypothesis test for the mean number of hours of TV that people watch in a day.

**Final Review**

Here is a practice final exam.

**Online Normal Distribution Calculators**

Here are some normal distribution calculators:

- OnlineStatBook.com, Normal Probabilities
- OnlineStatBook.com, Inverse Normal
- MathPortal.org, Normal Probability Calculator
- keison.casio.com, Normal Probability Calculator
- DavidMLane.com, Normal Distribution Calculator

The normal distribution grapher in the simulation may not work for some of you due to browers blocking it.
