Hi, I am wondering if the data points should be unique in a data set? Because I see there is a numeric data point repeated two time in the data set in the excel exercise file. Thanks.

Hi Timur, thanks for reaching out! You're asking a really valid question. The data points don't have to be unique in a data set. For example, if you have information on the height and weight of different people, it is perfectly reasonable to expect that two, or even more of the people will have the same height and weight. If you include their names for example, than the odds of that become slighter, so it also depends on the kind of data you have and what features it contains. Best, 365 Eli
