Population Analysis

  • For the 835,580 species in the Class Magnoliopsida (Dicotyledons), we average 4.30 observations each in our database; for the European Maple, we have 1,399 observations. Compared to other species in this Class, this species is extremely common.
  • A two-sample t-test can be used to determine whether the trend in observations of the European Maple is the same as the trend in observations of Magnoliopsida. Is this species just as common, as a proportion of all observations, as it once was? The answer is yes, changes in observation rate of this species do not significantly differ from changes in observation rate of its Class.
