1. Your graduate advisor once studied the distribution of fossil fishes in a section of sedimentary rock from the early Devonian period. She sampled 30 different sites at the same stratigraphic level, and described the data as follows: Mean number of fossils per square meter - 11.6 Standard deviation - 3.7 You take up the same question, but sample a range of sites from the late Devonian period. Your data for 10 sites are as follows: 15 Site Fossils/m 1 23 2 18 3 9 4 17 5 6 7 8 16 11 21 a. Calculate the mean, median, standard deviation, standard error and coefficient of variation for your sample. Hand-calculate and show your work, and confirm by providing appropriate JASP or other output. (10 points) 17 10 b. Which data set (early or late Devonian) is more variable? Justify your conclusion with logic and choice of the appropriate statistic(s) (5 points) 1.
