Video Lectures:

CLT refresh, intro to confidence intervals for mean. video / pdf of notes / single image of notes
   Note that the was a typo on the board in this video, with the calculation of a few of the t-statistics.
   I have fixed it in the notes, but will not re-record the video.

Confidence intervals for binomial proportion. video / image of notes

CI for difference in means, single variance. video / image of notes / COVID-19 state data

Intro to hypothesis testing. video / image of notes 

Hypothesis test for single mean, t-test. video / image of notes

Linear regression. video (*in progress*)



FREE Digital textbook access:

For free access to digital textbooks (good through May 25, 2020) sign up for a VitalSource account. You should be able to access most texts from most publishers. Here is more information: VitalSource Helps (go about 2/3 down to pink band on page). Sign up for a VitalSource Bookshelf account, and you can either download the local software or use a webrowser to view digital textbooks. There are also apps for various other devices. Bookshelf is their app for requesting access to and viewing digital testbooks.

I have successfully used VItalSource on both my laptop and phone.

Disclaimer: I haven't tested this free student access and do not know the exact procedure for gaining access to you textbooks digitally. It should NOT require any kind of payment information. Presumably, just create a Bookshelf account and there should be a way to search for your textbook and request access through that app. 


Scanning work for turning in:

When turning in scanned work via email or to Blackboard, please convert it into a single high resolution pdf document (per assignment). This will make it easiest for me to keep everything organized and to write comments on the work to send back to you.

CamScanner is an app that I use to scan from phone to pdf. You can take multiple pictures and it will output a single pdf. It's available for both Android and iPhone. I am sure there are many similar apps. This one leaves a watermark with the free version. That's fine.

If you have a local scanner, that should work too. I prefer 300dpi and color, but 150dpi may suffice. Please check your pdf document so that the work is legible. Sometimes small writing or light writing (such as soft pencil) doesn't scan well. I suggest using blue or black ink or a sufficiently dark pencil for your written work. You could even try photos of boardwork, but make sure to organize it into a single document (per assignment).
