Understanding Data Representation

How can a dot plot be used to find the median?

• By calculating the average of all dots

• By counting the dots

• By measuring the plot area

• By listing and ordering the values

Why is a histogram not suitable for finding the exact median?

• It only shows the highest value

• It groups data into intervals

• It cannot display numerical data

• It is only used for categorical data

Why can't the exact median be determined from a histogram?

• Because it only shows the mode

• Because it is not a graphical representation

• Because it lacks specific value details

• Because it only displays the mean

Which data representation explicitly indicates the median?

• Dot plot

• Histogram

• Box plot

• Bar chart

What does the middle line in a box plot represent?

• The median value

• The most frequent value

• The total range

• The average value

What is the median running time of Pixar's first 14 films according to the box plot?

• 95 minutes

• 96 minutes

• 99 minutes

• 100 minutes

What advantage does a box plot have over a histogram?

• It can display larger data sets

• It explicitly shows the median

• It is easier to draw

• It uses colors to represent data

How many vehicles had driven more than 200,000 kilometers?

• Five

• Seven

• Ten

• Three

Which display is more useful for finding how many vehicles exceeded a certain mileage?

• Dot plot

• Histogram

• Box plot

• Line graph

In the context of the used-car lot data, what information does the histogram provide that the box plot does not?

• The average mileage of all cars

• The total number of cars

• The number of cars in specific mileage ranges

• The exact median value
