💡 Hint

Common Mistakes

Importing the wrong function like ttest_ind instead of f_oneway.

Using a function for correlation or regression instead of ANOVA.

The f_oneway function is used to perform one-way ANOVA in scipy.stats.

medium

Complete the code to perform ANOVA on three groups: group1, group2, and group3.

SciPy

stat, p = f_oneway([1], group2, group3)

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

💡 Hint

Common Mistakes

Using a variable name that does not exist like data1.

Passing the wrong variable as the first argument.

The first argument to f_oneway should be the first group of data, here named group1.

3fill in blank

hard

Fix the error in the code to correctly perform ANOVA on groupA, groupB, and groupC.

SciPy

result = f_oneway(groupA, [1], groupC)

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

AgroupB

BgroupC

CgroupA

DgroupD

Attempts:

💡 Hint

Common Mistakes

Repeating groupC or groupA instead of using groupB.

Using a group name that does not exist.

The second argument should be groupB to include all three groups in the ANOVA test.

4fill in blank

hard

Fill both blanks to create a dictionary with keys 'statistic' and 'pvalue' from the ANOVA result.

SciPy

anova_result = {'statistic': result.[1], 'pvalue': result.[2]

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

Astatistic

Bpvalue

Cp_value

Dstat

💡 Hint

Common Mistakes

Using 'p_value' instead of 'pvalue'.

Using 'stat' instead of 'statistic'.

The ANOVA result object has attributes statistic and pvalue to access the F-statistic and p-value.

5fill in blank

hard

Fill all three blanks to perform ANOVA on data1, data2, data3 and print the p-value.

SciPy

stat, [1] = f_oneway([2], [3], data3)
print('P-value:', p)

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

💡 Hint

Common Mistakes

Assigning p-value to a wrong variable name.

Swapping the order of data1 and data2.

The function returns statistic and p-value; assign p-value to p. The groups are data1, data2, and data3.
