Tutorial: Data Cleaning 

You covered different types of data in a short period of time. This video served my needs well. Thank you.

Really great video. Thanks for simplifying it so much.

I do not agree that you automatically calculated for the mean score and used it to fill in the missing value in the data set. What about looking at the answers from other observations with similar conditions and using these info to guess what the missing value should be.

Thanks Meredith Rocchi, This video helps me a lot
