Permutations and Combinations

If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.

Counting Theory

The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.

Meta-analysis refers to the statistical analysis of a set of similar
research studies. In a meta-analysis, each data value
represents an effect size calculated from the results of a
particular study. The table contains effect sizes calculated in a
meta-analysis for zooplankton and phytoplankton.
By constructing the boxplots for both zooplankton and
phytoplankton data, which type of plankton seems to have the
greater overall effect sizes?
Select one:
Phytoplankton data
Zooplankton data
Both have approximately the same effect size
