hard

Fix the error in the code to set the number of bins to 5 in the histogram.

Data Analysis Python

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

💡 Hint

Common Mistakes

Passing bins as a string like '5' instead of an integer.

Using an expression like bins=5 inside the argument list.

The bins parameter expects an integer number, not a string or expression.

4fill in blank

hard

Fill both blanks to create a histogram with 4 bins and set the color to blue.

Data Analysis Python

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

💡 Hint

Common Mistakes

Using color without quotes.

Setting bins to a string instead of a number.

We set bins to 4 and color to 'blue' as a string to customize the histogram.

5fill in blank

hard

Fill all three blanks to create a histogram with 6 bins, green color, and add a title 'My Histogram'.

Data Analysis Python

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

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