What is the purpose of the color_palette() function in Seaborn?
To plot the data using a specific color palette
What are the different types of color palettes in Seaborn?
Qualitative, Sequential, and Diverging
Which Seaborn function is used to plot the color palette as a horizontal array?
palplot()
What is the purpose of a qualitative color palette in Seaborn?
To plot categorical data
How can you specify the number of colors to be used in a Seaborn color palette?
By passing the n_colors parameter to the color_palette() function
What is the purpose of a sequential color palette in Seaborn?
To express the distribution of data from lower to higher values
What type of plot is the most convenient way to visualize the distribution of two variables in a two-dimensional plot with x and y axes?
Scatter Plot
Which type of plot is used in bivariate data analysis when the data is sparse in density and scattered, making it difficult to analyze through scatterplots?
Hexbin Plot
In seaborn, what parameter and value combination is used to plot a hexbin plot in a joint plot?
'kind'='hex'
What type of plot is a non-parametric way to estimate the distribution of a variable?
Kernel Density Estimation
Which plot projects the bivariate relationship between two variables and also displays the univariate distribution of each variable on separate axes in a multi-panel figure?
Scatter Plot
When visualizing the relationship between petal_length and petal_width in the Iris dataset, which type of plot indicates a positive correlation between the variables?
Scatter Plot
What does the hue parameter in sns.violinplot() represent?
The categorical variable used to group the data
What type of plot is used when one of the variables under study is categorical?
Stripplot
What visual difference can be observed when using split=True in sns.violinplot()?
The violin plot is split into two halves, representing the two categories of the hue variable
What is the purpose of the sb.set_style("ticks") function call?
To set the style of the plot to use ticks on the axes
What does the y parameter in sns.violinplot() represent?
The numerical variable to be plotted on the y-axis
What is the purpose of the plt.show() function call?
To display the plot on the screen
What is the purpose of the sns.load_dataset() function?
To load one of the built-in datasets provided by Seaborn
What is the purpose of the sb.pairplot() function call?
To create a scatter plot matrix
What statistical concept is represented by a violin plot?
Distribution shape
What is the purpose of the plt.show() function in the provided code?
To display the plot in a new window
What is the purpose of the diag_kind="kde" parameter in the sb.pairplot() function call?
To use a kernel density plot for the diagonal plots
What is the purpose of the kind="scatter" parameter in the sb.pairplot() function call?
To use a scatter plot for the off-diagonal plots
