Give me an example of when you would use neural networks.
BASIC DATA SCIENCE INTERNSHIP QUESTION HOW TO
Note that an interviewer may ask you further questions about logistic regression to see if you know how to apply it in real-world settings.ĥ. Another example is a doctor or nurse using it to indicate whether or not a patient will respond to a particular treatment. For example, it can predict the likelihood of a customer making a purchase. Logistic regression is a statistical model used to predict the probability of a binary outcome. What’s your understanding of logistic regression? Machine learning algorithms can learn from data and make predictions, while data mining algorithms are only able to find patterns in data.Ĥ. To answer this question, you should explain that machine learning is a more advanced form of data mining. What’s the difference between data mining and machine learning? Ideally, when answering this question, you should also give a real-world example of how root cause analysis can be applied-for example, in medical mistakes, manufacturing mistakes, etc.ģ. For example, root cause analysis can be used in data science to determine the factors that contribute to a particular outcome. Data analysts provide decision support to business by compiling and displaying data in visual charts, while data scientists go one step further-developing and designing new processes and predictive models based on their analyses.įirst, you want to explain that root cause analysis is a method used to identify the underlying causes of problems or issues. Then you want to discuss the differences, namely that data science is a more interdisciplinary field than data analytics.
To answer this question, you should first explain that data analysts and data scientists both analyze data. This question tests your understanding of these two areas and two related roles. What’s the difference between data analytics and data science? And if you're looking to land a job in data science engineering this year, you'll need to be able to answer the following six interview questions-which cover a wide range of topics, including machine learning, statistics, and database design.ġ. Data science is one of the fastest-growing career paths.
