Answers

Answer 1

His run this week was two standard deviations below the mean.

What is standard deviation
Standard deviation is a measure of variability or spread in a set of data. It is the square root of the variance, which is calculated by taking the average of the squared differences between each value in a dataset and the mean (average) of the dataset. Standard deviation is a useful tool in statistics and mathematics to measure how spread out the values in a dataset are. It is also used to measure the risk of a particular investment, or the variability of returns. Standard deviation is a measure of how much a set of data points vary around the mean. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. The higher the standard deviation, the more spread out the data is.

Verbatim Theatre Style.
What is it?
How is it different?
This is for my Drama class. Need it ASAP!!!!

Answers

Answer:

Verbatim Theatre is a theatrical style that is based on actual transcripts or recordings of real events, interviews, or speeches. This type of theatre is meant to capture the exact words and expressions of the individuals being portrayed, creating a highly accurate and true-to-life representation. The scripts are created by transcribing, editing, and arranging the source material into a dramatic format.

Verbatim Theatre is different from other forms of theatre in several ways. First, it is often used to address political or social issues, providing a platform for marginalized voices to be heard. Second, it is heavily reliant on the spoken word, and the performance style is often minimalistic, allowing the focus to remain on the content of the words being spoken. Third, the material used in Verbatim Theatre is often based on current events or recent history, giving it a feeling of immediacy and relevance.

Overall, Verbatim Theatre is a unique and powerful form of theatre that allows for the exploration of current issues and provides a platform for voices that may not be heard in mainstream media.
