A#36 Dot Plot, Histogram, Box Plot

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots plotted above a number line, where each dot represents a data point.

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, showing the frequency of data points within specified ranges (bins).

Front

What is a box plot?

Back

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.

Front

What is the lower quartile (Q1)?

Back

The lower quartile (Q1) is the median of the lower half of a data set, representing the 25th percentile.

Front

How do you calculate the range of a data set?

Back

The range is calculated by subtracting the minimum value from the maximum value in the data set.

Front

What is the median of a data set?

Back

The median is the middle value when the data points are arranged in ascending order; if there is an even number of data points, it is the average of the two middle values.

Front

What does it mean if a data set is approximately symmetrical?

Back

A data set is approximately symmetrical if its left and right sides are mirror images of each other, indicating that the mean and median are close in value.

Front

What is the mode of a data set?

Back

The mode is the value that appears most frequently in a data set.

Front

How do you interpret a dot plot?

Back

A dot plot can be interpreted by counting the number of dots above each value to determine frequency and identifying patterns in the data.

Front

What does a wider box in a box plot indicate?

Back

A wider box in a box plot indicates a greater interquartile range (IQR), meaning there is more variability in the middle 50% of the data.
