The table shows the test scores of students who studied for a test as a group (group a) and students who studied individually (group b). which would be the best measures of center and variation to use to compare the data? the scores of group b are skewed right, so the mean and range are the best measures for comparison. both distributions are symmetric, so the mean and the standard deviation are the best measures for comparison. both distributions are symmetric, so the median and the interquartile range are the best measures for comparison. the scores of both groups are skewed, so the median and standard deviation are the best measures for comparison.

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
