Importance of probability in data science



How much important the probability for data scientists ?
in which area probability is widely used ?


Hi jitesh2k12,

The basic of probability is very use full in Data Science. The Data scientists use machine learning algorithms for modelling. All machine learning algorithms are directly or indirectly dependent on probability based concepts. For example Naive Base algorithm directly use probability of positive and negative to calculate the posterior probability.



Probability is everything you are after. From a basic x vs y relationship to multiple variable relationship. The way you achieve it is the process of data science but our ultimate goal is there is a dependent variable and there are independent variables and then you find a way to predict the dependent variable either at a point of time or other but ultimately you are simply creating probability.

Everything else you learn is basically drilled down to probability statistically.
