Questions and Answers

Which type of data visualization displays the median, the interquartile range, and the range of the data for one factor/variable?

Box plot (correct)
Density plot
Violin plot
Histogram

What is the main difference between a density plot and a histogram?

Density plots show the distribution of multiple variables
Density plots are smoother than histograms (correct)
Histograms display the median and interquartile range
Histograms are used for continuous data

Which type of data visualization displays the density of data for one variable/factor, similar to a box plot?

Histogram
Density plot
Violin plot (correct)
Box plot

Match the following data visualisation types to their descriptions:

Histogram = Represents distribution of one factor/variable Density Plot = A 'smoothed' histogram Box Plot = Displays the median, the interquartile range, and the range of the data from one factor/variable Violin Plot = Similar to a box plot but also displays the density of data for one variable/factor Signup and view all the answers

Match the following data visualisation types to what they can display or represent:

Histogram = Distribution of a single variable Density Plot = Smoothed view of data distribution Box Plot = Median, interquartile range, and range of a single variable Violin Plot = Density and distribution of data for a single variable Signup and view all the answers

Match the following data visualisation types to the aspects they can detect or show:

Histogram = Distribution Density Plot = Smoothed distribution Box Plot = Outliers Violin Plot = Density of data Signup and view all the answers

Match the following individuals with their contributions to data visualization:

Florence Nightingale = Invented the 'polar' or 'artic' plot and linked deaths to poor sanitisation Dr John Snow = Mapped cholera outbreaks from nineteenth century London, linking the disease to a contaminated water pump Professor Hannah Keage = Delivered a lecture on data visualisation, covering its principles and common methods Signup and view all the answers

Match the following principles of data visualization with their descriptions:

Guided by scientific questions = The visualization should aim to answer specific research questions, not just present data randomly Aesthetics = Attention should be given to colours, taking into account factors like colour blindness Show the distribution = Rather than just showing summary statistics like the mean, the distribution of data should be displayed Signup and view all the answers

Match the following reasons for visualising data with their explanations:

Discover patterns = Visualization allows us to identify trends and regularities in the data Thinking deeply about the data = Visualization encourages a more profound understanding of the data See differences between groups and individuals = Visualization can highlight disparities and similarities within and between data subsets Communication = Visualization serves as a medium for telling a story and presenting findings to others Signup and view all the answers
