Reason. The PyPlot interface of matplotlib library is used for 2D plotting.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Assertion. A scatter chart simply plots the data points on a chart to show the trend in the data.

Reason. A line chart connects the plotted data points with a line.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Assertion. For the same sets of data, you can create various charts using plot(), scatter(), pie(), bar() and barh().

Reason. All the data sets of a plot(), scatter(), bar() cannot be used by pie() ; it will work with only a single set of data.

3. A is true but R is false.
4. A is false but R is true.

Assertion. Five-point statistical summary of a data set can be visually represented.

Reason. The boxplot() function can plot the highest and lowest numbers of a data range, its median along with the upper and lower quartiles.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.
