MLS-C01 Exploratory Data Analysis Practice Question

A data scientist is exploring a dataset and wants to understand the distribution of a continuous feature. Which visualization is most appropriate for identifying skewness and potential outliers?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Box plot

(bar chart) is wrong because bar charts are for categorical data, not for showing distribution of a continuous feature. Option B (scatter plot) is wrong because scatter plots show relationships between two variables, not distribution. Option C is correct because a box plot explicitly shows median, quartiles, and outliers. Option D is wrong because heatmaps show correlations, not distribution.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Bar chart

    Why it's wrong here

    Bar charts are for categorical data, not for showing distribution of a continuous feature.

  • Scatter plot

    Why it's wrong here

    Scatter plots show relationships between two variables, not distribution.

  • Box plot

    Why this is correct

    A box plot explicitly shows median, quartiles, and outliers, making it ideal for identifying skewness and potential outliers.

  • Heatmap

    Why it's wrong here

    Heatmaps show correlations between variables, not the distribution of a single continuous feature.
