# Which of these are the characteristics of a Binomial Experiment? ## Which one of these are the characteristics of a binary experiment?

A binomial experiment is one in which all four of the following conditions are met: The experiment consists n identical trials. Each trial produces one of two outcomes: success or failure. From trial to trial, the probability of success (denoted p) remains the same.

### Which of the following is not a characteristic of a binomial?

i. “The likelihood of failure may vary from trial to trial” does not represent a binomial distribution.

#### What is not a binomial experiment?

A non-binomial experiment may be considered binomial if the results of each trial are stated in a binomial format. A non-binomial example might be: “Count the heads and tails that result from 8 flips on a fair coin.”

What are the 4 characteristics of a binomial distribution?

What is the skewness of normal distribution?

### Why do we use standard scores?

The standard score, also known as a “z-score”, is an extremely useful statistic that allows us to determine the probability of a score appearing within our normal distribution. It also allows us to compare scores from different normal distributions.
