Descriptive Statistics: Statistical Measurements and Probability Distributions
These measures can help indicate where the bulk of the data is concentrated and are often called the data’s central tendency .
Practice this chapterThese measures can help indicate where the bulk of the data is concentrated and are often called the data’s central tendency . The mean , or average, (sometimes referred to as the arithmetic mean ) is the most commonly used measure of the center of a dataset.
probability — a numerical measure that assesses the likelihood of occurrence of an event. probability distribution — a mathematical function that assigns probabilities to various outcomes. descriptive statistics — the organization, summarization, and graphical display of data. trimmed mean — a calculation for the average or mean of a dataset where some percentage of data values are removed from the lower and upper end of the dataset; typically used to mitigate the….
Be able to calculate the mean of the dataset; calculate a 20% trimmed mean rate for the dataset.
Worked example
What does “probability” mean in Descriptive Statistics: Statistical Measurements and Probability Distributions?
- 1Use the wording this chapter gives for probability.
- 2The book says: a numerical measure that assesses the likelihood of occurrence of an event.
- 3Do not use the meaning of probability distribution. That term means a mathematical function that assigns probabilities to various outcomes.
Result: a numerical measure that assesses the likelihood of occurrence of an event
Why. That is the meaning this chapter gives for probability.
Do not swap probability and probability distribution. probability means a numerical measure that assesses the likelihood of occurrence of an event. probability distribution means a mathematical function that assigns probabilities to various outcomes.
