930 Unit 3.5 Day 4: Scatter Plots, Histogram, Box & Dot Plots

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional grid.

Front

What is a histogram?

Back

A histogram is a type of bar graph that represents the frequency distribution of numerical data by showing the number of data points that fall within specified ranges (bins).

Front

What is a box plot?

Back

A box plot (or box-and-whisker plot) is a graphical representation of data that shows the median, quartiles, and potential outliers in a dataset.

Front

What is a dot plot?

Back

A dot plot is a simple statistical chart that consists of dots representing the frequency of data points along a number line.

Front

What is the upper quartile (Q3)?

Back

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

Front

What is the lower quartile (Q1)?

Back

The lower quartile (Q1) is the median of the lower half of a dataset, representing the value below which 25% of the data falls.

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest data point in a dataset.

Front

What does a negative association in a scatter plot indicate?

Back

A negative association indicates that as one variable increases, the other variable tends to decrease.

Front

How do you determine the frequency of a value in a histogram?

Back

The frequency of a value in a histogram is determined by counting how many data points fall within each bin.

Front

What is the purpose of a box plot?

Back

The purpose of a box plot is to provide a visual summary of the central tendency, variability, and distribution of a dataset.
