You wish to test if there is a relationship between soil temperature and plant abundance, so you measure soil temperature in 30 different plots within the forest, and count the number of plants in each plot. To test your hypothesis that plant abundance increases as soil temperature increases, you would make a and run a scatterplot; v-test O scatterplot; linear regression bar graph; t-test

5
You wish to test if there is a relationship between soil temperature and plant abundance, so you
measure soil temperature in 30 different plots within the forest, and count the number of plants in
each plot. To test your hypothesis that plant abundance increases as soil temperature increases, you
would make a
and run a
scatterplot; v-test
O scatterplot; linear regression
bar graph; t-test
Question 2
You hypothesize that there will be more species of plants at a site far from the trail (50 meters) than
a site close to the trail (10 meters). You collect data from 10 plots located 10m from the trail and 10
plots located 50m from the trail, and compare the averages from each category. Which type of graph
would you make, and which statistical test would you run on your data?
bar graph; t-test
scatter plot; linear regression
O scatter plot; v-test
