In this lesson, Ashna introduces three types of graphs: dot plots, box plots, and histograms. She explains the components and construction of each graph type, starting with box plots, which display the minimum, maximum, and median of a data set. Dot plots are then discussed, showing how each dot represents a data value's frequency. Finally, histograms are introduced as a bar graph form of dot plots, illustrating data frequency. The lesson includes examples and exercises to help learners understand and create these graphs.

What does a box plot display?

• Data divided into ten parts

• Minimum, maximum, and median of a dataset

• Frequency of data as bars

• Each data value as a dot

What is the median in a dataset?

• The most frequent value

• The difference between the highest and lowest values

• The middle value when data is ordered

• The average of all values

How is the interquartile range calculated in a box plot?

• Median of the upper half minus median of the lower half

• Upper quartile minus lower quartile

• Sum of all values divided by the number of values

• Maximum minus minimum

How do you determine the number of people with two brothers and sisters using a dot plot?

• Look for the color code at point two

• Count the bars at point two

• Count the dots at point two

• Measure the height of the dot at point two

In a dot plot, what does each dot represent?

• The frequency of a data value

• A unique data value

• A category of data

• The average of two data points

What is the main difference between histograms and dot plots?

• Histograms can only show numerical data, while dot plots can show any type of data

• Histograms show individual data points, while dot plots show grouped data

• Histograms use bars to show frequency, while dot plots use dots

• Histograms are used for large datasets, while dot plots are for smaller datasets

How do you read the frequency of a specific value in a histogram?

• By the color of the bar

• By the height of the bar

• By the number of bars

• By the width of the bar
