Question 1

is studied to bridge the gap between descriptive statistics and statistical inference

Answer 1

Theory Of Probability

Question 2

✔ Order matters → The arrangement or sequence of items is important.
✔ You are selecting or arranging items in a specific order.

Answer 2

PERMUTATION

Question 3

✔ Order does NOT matter → The group selection is important, but not the arrangement.
✔ You are choosing items without arranging them in a particular order.

Answer 3

COMBINATION

Question 4

Question 7

a binomial distribution with 1 trial

Answer 7

Bernoulli distribution

Question 8

• can be thought of as the probability of success or failure outcome in independent repeated trials

Answer 8

Binomial distribution

Question 9

• almost similar with binomial except it does not require independence among trials

Answer 9

Hypergeometric distribution

Question 10

• almost the same as binomial distribution except the number of trials is not fixed
• the number of failures before you get a success in a series of Bernoulli trials
  • gives the probability of a given number of events happening in a fixed interval of time or region

Answer 10

Negative Binomial distribution

Geometric distribution

Poisson distribution
