Focus On Story Telling-How To Ace Data Science Interviews?

Data storytelling is a methodology for communicating information, tailored to a specific audience, with a compelling narrative. It is the last ten feet of your data analysis and arguably the most important aspect. Evolutionarily, as Humans, we are naturally hard-wired to share stories as a means of sharing information.

Stock market scenario:
Case 1 : we have predicted it will crash ,but it did not (False Positive) . Focus on precision score.
Case 2 : we have predicted it will not crash ,but it crashed (False Negative) .
This will do more damage than case 1.
Hence, we need to Keep FN low (high Recall) .
Case 3: If client specifically wants a balance i.e we don't want too many FP or FN . Focus on F1 score.

Thank you so much for your valuable advice in this tough time. Much needed video

[@admitra7512]

Hello sir, in response to the question asked,here is my answer.
so the problem statement is to predict whether the stock market will crash or not.
here the FALSE POSITIVE would be/Type 1 error rate would be: our model predicts that the stock market crashes but in reality it does not crash(predicting something true when in reality it is false).
here the FALSE NEGATIVE would be/Type 2 error rate would be: our model predicts that stock market wont crash but in reality it crashes(predicting something false when in reality it is true).
so in context of the stakeholder or someone who is really into buying stocks,that person would try to minimise the False Negative rate as it brings much more harm to that person, as a lot of money is attached to the stock market,perhaps.

Can u talk data pipelines in story telling ...how data we are getting.

[@tanvishinde805]

stock market : False Positive should reduce , i.e. a rising stock price, if predicted with a fall in price would do more harm

[@juhitaksande5032]

[@purushothamreddycheppala6521]

Krish bro how could we introduce our data science portfolio in interview

[@pdpy4550]

If the interviewer asks you, tell me about yourself, then start with the best project that you had done and have an end to end knowledge of it. because the next question they ask will from that project only and as you have an end to end knowledge of it, you can answer it easily.it also help you to build confidence.

Stock market false positive

[@kaustubhgupta12]

If we talk about whether the stock market will crash or not, shouldn't we foucs on reducing false negatives as FN are cases where the predicted result was falsely labeled as negative and in this case, if the stock market crashes and the model predict that it doesn't crash, it will make no sense. Kindly correct me if you have other analogies
