Question

As noted in the readings, bad data could lead to bad predictions.  

Give an example of bad data that led to a bad prediction. Cite your source.  

Answer 1

If the data collected is wrong, it can lead to wrong predictions during the research time.
Example: One had to calculate the number of commuters taking the taxis each day. The data collected for the day was of the people taking taxis for work in the morning. (Obsuszt, 2020)
The wrong data was collected as the number of people taking back the taxis from the work was not calculated and hence the predictions made for launch of a new taxi was reached to be wrong.
Hence, while making a decision, it becomes essential to have a correct and verified data set.
