[00:07:25] Let’s say we’re working with an e-commerce company. They’re seeing a high rate of cart abandonment – that’s when customers add items to their online shopping cart but never make it to the checkout. Sounds like a mystery, right?

[00:07:37] Enter our data scientist. They start by collecting data – user demographics, browsing behavior, the time of day, the items in the cart – everything.

[00:07:46] Then comes the detective work. They analyze the data, looking for patterns. Do people abandon their carts more often at certain times of day? Are there specific items that are often left unpurchased?

[00:07:58] I know what you’re thinking. Is this a Sherlock Holmes story or a data science case study? Well, actually this is one of the typical types of problems data scientists face on a day to day basis.

[00:08:09] And now back to our case study. Well, our data scientist discovers that many customers are abandoning their carts because of unexpected shipping costs. Aha! The plot thickens.

[00:08:21] Based on this insight, the company decides to offer free shipping for orders over a certain amount. And voila! The rate of cart abandonment decreases.

[00:08:30] There you have it, folks, data science in action! It’s not just about crunching numbers. It’s about solving real problems, making a real impact.

[00:08:39] Next up, we’re going to tackle a big question – is a career in data science right for you? Stay tuned because this next segment might just help you uncover your destiny!
