There is a new poll out saying that 73% of Americans approve of new legislation. 4 out of 5 Dentists like whitening toothpaste. That new film has a rating of 4.5 stars.
We are inundated with data. So it behooves us to be able to understand the data that is presented.
For instance, for the statement 4 out of 5 dentists like whitening toothpaste. How many dentists were really asked? If they really only asked 5 dentists and four dentists like it, do you think dentists really like whitening toothpaste. What if they asked 5,000 dentists, and 4,000 dentists like it?
And that's not all!
Your streaming service is giving you increasingly good recommendations. And your map app warns you about traffic on your route.
That's Big Data. Your streaming service knows what you've watched on it. As you use it, it knows more and more about what you like to watch. It is comparing you to other people who watched the same shows to recommend other shows that those people have watched.
Our behavior online is data. And not just when we order from Amazon, but when we use wearable electronics (like Fitbit), use smart speakers, download apps, and more. So we need to remember that and be careful with our data.
