Can Kuest run my Jupyter notebook?

No. Kuest doesn't execute code or load your files. Paste the code, the error and a few rows of output, like the result of df.head() or df.describe(), and Kuest helps you interpret it and decide what to try next.

Do I need to know statistics first?

Not all of it. Kuest teaches the statistics as you need it, starting with mean, median and spread, and adds hypothesis testing and regression when your analysis calls for them.

Does Kuest teach R as well as Python?

Yes. Kuest can explain R and the tidyverse too, and can translate between dplyr and pandas if your class uses one and you know the other.

Can it help me write up my findings?

Kuest helps you check that your conclusion matches your evidence, asks about limitations and helps you explain uncertainty clearly. The writing stays yours.

How is Kuest different from Kaggle Learn or DataCamp?

Kaggle Learn and DataCamp offer structured courses with exercises that run in the browser, and Kaggle adds real datasets and competitions. Kuest doesn't run code; it's a tutor that explains your own analysis, quizzes you on the statistics and adapts to your gaps. They pair well.

How is Kuest different from ChatGPT?

ChatGPT answers. Kuest teaches: it asks what you think first, checks every step, turns what you learned into quizzes and flashcards, and remembers what you got wrong so it comes back to it. It also grades your answers on our servers, so it never shows you the answer before you try.

Does one plan cover every subject?

Yes. Free and paid plans include every subject, exam and skill on this site. Switch subjects any time and each one keeps its own history.

Is Kuest safe for students under 18?

It's built for them. There are no ad trackers in the app, we keep personal details out of logs and AI traces, and parents can link their account to follow progress without reading every chat.

Can Kuest replace a tutor or teacher?

It's there for the hours a tutor or teacher can't be: late-night homework, the week before a test, the question you didn't want to ask in class. Many students use it alongside their teacher, not instead of them.

See how Kuest teaches it

It asks before it tells, so you do the thinking and it sticks.

My dataset's average income is $95,000 but the median is $52,000. Which one should I report?

Good catch that they differ so much. What would have to be true about the data for the mean to be that much higher than the median?

Maybe a few people have really high incomes?

That's the usual reason. How could you check that in pandas or with a chart?

df["income"].describe() to see the max and quartiles, or a histogram to see if it's skewed right.

Exactly. If it's right-skewed, the median better describes a typical person, and you can mention the mean to show the skew.

In skewed data the mean gets pulled toward the tail, so the median usually describes the typical value better.

The method

How to study Data science with Kuest

Data science is part coding, part statistics and part judgment. Learn it by asking a question of a real dataset, predicting what you'll see before you plot it, and explaining the result in plain words. Review the statistics regularly, since that's where most misreadings come from.

Paste your code and outputTutor chat
Share the pandas code, the error or the table it printed. Kuest asks what you expected and helps you read what the data shows.
See the distributionGraphs
Kuest graphs distributions, scatter plots and regression lines so you can see skew, outliers and trends.
Snap a chart or slideSnap a photo
Take a photo of a chart from class or a paper and ask what it shows and what it doesn't.
Check your statisticsQuizzes
Quizzes on p-values, confidence intervals and chart choice build the judgment that code alone doesn't give you.
Listen on the goPodcasts
Turn your lecture notes into a podcast that reviews concepts like sampling bias and regression.
Remember the pandas APIFlashcards
Spaced flashcards for loc versus iloc, groupby, merge and common statistics terms keep them within reach.
