Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a scatter plot using matplotlib.

Data Analysis Python

import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [10, 20, 25, 30]
plt.[1](x, y)
plt.show()

💡 Hint

Common Mistakes

Using plt.plot() which creates a line plot instead of scatter plot.

Using plt.bar() which creates bar charts, not scatter plots.

The scatter function creates a scatter plot by plotting points at the given x and y coordinates.

medium

Complete the code to add labels to the x and y axes in the scatter plot.

Data Analysis Python

import matplotlib.pyplot as plt
x = [5, 7, 8, 7, 2]
y = [99, 86, 87, 88, 100]
plt.scatter(x, y)
plt.xlabel([1])
plt.ylabel('Scores')
plt.show()

💡 Hint

Common Mistakes

Forgetting to put the label text inside quotes.

Using the wrong label that does not match the data.

The x-axis label should describe the data on the x-axis. Here, it is 'Age'.

hard

Fix the error in the code to correctly plot a scatter plot with red points.

Data Analysis Python

import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [10, 20, 25, 30]
plt.scatter(x, y, color=[1])
plt.show()

💡 Hint

Common Mistakes

Passing color without quotes causing a NameError.

Using full color name without quotes.

The color argument requires a string, so it must be in quotes. 'r' is a shorthand for red color.

4fill in blank

hard

Fill both blanks to create a scatter plot with blue points and size 100.

Data Analysis Python

import matplotlib.pyplot as plt
x = [2, 4, 6, 8]
y = [5, 15, 25, 35]
plt.scatter(x, y, color=[1], s=[2])
plt.show()

Drag options to blanks, or click blank then click option'

A'blue'

B50

C100

D'green'

💡 Hint

Common Mistakes

Using color without quotes.

Setting size too small to notice.

The color is set to 'blue' as a string, and the size s is set to 100 for larger points.

5fill in blank

hard

Fill all three blanks to create a scatter plot with green points, size 80, and alpha transparency 0.5.

Data Analysis Python

import matplotlib.pyplot as plt
x = [1, 3, 5, 7]
y = [2, 4, 6, 8]
plt.scatter(x, y, color=[1], s=[2], alpha=[3])
plt.show()

Drag options to blanks, or click blank then click option'

A'green'

B80

C0.5

D'yellow'

💡 Hint

Common Mistakes

Passing color without quotes.

Using alpha values outside 0 to 1 range.

Setting size too small or too large.

The color is 'green' as a string, size s is 80 for medium points, and alpha 0.5 makes points semi-transparent.
