Dot Plot, Histogram, Box Plot

A dot plot is a statistical chart that uses dots to represent the frequency of data points in a dataset. Each dot represents one occurrence of a value.

A histogram is a graphical representation of the distribution of numerical data, where the data is divided into bins or intervals. The height of each bar represents the frequency of data points within that interval.

A box plot, or whisker plot, is a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

The upper quartile (Q3) is the median of the upper half of a dataset, representing the value below which 75% of the data falls.

To calculate the mean, sum all the values in the dataset and then divide by the number of values.

The median is the middle value of a dataset when it is ordered from least to greatest. If there is an even number of values, the median is the average of the two middle values.

The mode is the value that appears most frequently in a dataset. A dataset may have one mode, more than one mode, or no mode at all.

The range is found by subtracting the smallest value in the dataset from the largest value.

A frequency distribution is a summary of how often each value occurs in a dataset, often represented in a table or graph.

A box plot visually summarizes the distribution of a dataset, highlighting the median, quartiles, and potential outliers.
