medium

Complete the code to create a histogram of the data list.

Matplotlib

data = [1, 2, 2, 3, 3, 3, 4, 4, 4, 4]
plt.[1](data)
plt.show()

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

💡 Hint

Common Mistakes

Using plot which makes a line graph

Using scatter which makes a scatter plot

Using bar which makes bar charts but not histograms

The hist function creates a histogram to show data distribution.

3fill in blank

hard

Fix the error in the code to correctly label the x-axis.

Matplotlib

plt.hist(data)
plt.xlabel([1])
plt.show()

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

A'Values'

Bxlabel

Cx_label

DValues

💡 Hint

Common Mistakes

Using variable names without quotes

Using incorrect function names

Forgetting quotes around label text

The label text must be a string, so it needs quotes.

4fill in blank

hard

Fill both blanks to create a histogram with 5 bins and a title.

Matplotlib

plt.hist(data, bins=[1])
plt.title([2])
plt.show()

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

B'Data Distribution'

C'Histogram'

D10

💡 Hint

Common Mistakes

Using too many bins like 10

Not putting the title in quotes

Confusing bins with title

Setting bins to 5 groups data into 5 parts. The title must be a string.

5fill in blank

hard

Fill all three blanks to create a histogram with green color, 8 bins, and x-axis label 'Scores'.

Matplotlib

plt.hist(data, bins=[1], color=[2])
plt.xlabel([3])
plt.show()

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

A8

B'green'

C'Scores'

D'blue'

💡 Hint

Common Mistakes

Using color without quotes

Using numbers instead of strings for labels

Mixing up color names

Bins is a number (8), color is a string ('green'), and xlabel is a string ('Scores').
