![Density of Water-Linear Regression [AP Biology 1.1]](https://i.ytimg.com/vi/qZnHnrlQ-IQ/mqdefault.jpg "Density of Water-Linear Regression [AP Biology 1.1]
Hi biology friends! I created this tutorial video covering how you can use Google Sheets to perform linear regression analysis.
The data set Ive analyzed in this video was from my trial run of a new lab for AP Biology. In the lab, students use micropipettes to transfer water into a test tube in 200 ÎĽL (0.200 mL) increments. The mass of the water is measured after each transfer. I will add a link to the video summarizing this lab when I finish it.
Coming Soon! Determining the Density of Water - AP Biology Lab
Density is one of the important emergent properties of water covered in Unit 1.1 of the AP Biology Course & Exam Description (CED).
