Description
I have a slide show that explains everything below. I also have the labpractical code and the data base
Lab practical QuestionsWrite an R script to test the following research questions (using a correlation and regression analysis):
1.Are elevation (elev) and vegetation dryness (VARI) correlated?
2.Is distance to riparian area (dist_rip) correlated with chaparral recovery (NDVI)?
3.Does vegetation dryness (VARI) affect chaparral recovery (NDVI)? What is the NDVI of a plot with VARI of 16.5?
4.Does drought (CWD) affect chaparral recovery (NDVI)? What is the NDVI of a plot with CWD of -4.6?
5.Does distance to road (dist_road) affect chaparral recovery (NDVI)? What is the NDVI of a plot that is 30 kilometers from the nearest road?
6.Does NDVI appear normally distributed? (hint: histogram)
7.Is there a visual difference in NDVI between high and low elevations (high_low)? (hint: boxplot)
