After reading this module you should be able to E xplain the difference between a fundamental and a realized niche D escribe how environmental change can alter species distributions D iscuss . Change over time…. Geology. Began to study rock layers called strata. George Cuvier. Studied fossils. Found extinct species and noticed the deeper the fossil the more unique. Catastrophism. Charles Lyell. Objective. : . To solve multistep probability tasks with the concept of geometric distributions. CHS Statistics. A . Geometric probability model. . tells us the probability for a random variable that counts the number of . Continuous distributions. Sample size 24. Guess the mean and standard deviation. Dot plot sample size 49. Draw the population distribution you expect. Sample size 93. Sample size 476. Sample size 948. A Brief Introduction. Random Variables. Random Variable (RV): A numeric outcome that results from an experiment. For each element of an experiment’s sample space, the random variable can take on exactly one value. Maryam . Aliakbarpour.
