Dr. Barton hypothesizes that if 1st grade students are assigned to practice sight word flashcards for 10 minutes every day for their first semester, they will end up reading more books in their second semester. She creates two groups of 25 students each and gives each group the same sight word flashcards. Group A is assigned to practice with the flashcards for 10 minutes every day for their first semester. Group B is not given this assignment. Each group is tasked with keeping a reading log during their second semester. At the end of 1st grade, Dr. Barton counts how many books each group has read. Group A read 68 books, and Group B read 92 books. The control group is: The independent variable is: The dependent variable is: This study shows that there is a positive correlation between 10 minutes of daily flashcard practice of sight words and the amount of books read.

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.
