Round 2 - Technical 

(5 Questions)

  • Q1. Explain Assumptions of Linear Regression
  • Ans. 

    Assumptions of linear regression are important for the model to be valid and reliable.

    • Linear relationship between independent and dependent variables

    • Independence of residuals (errors)

    • Homoscedasticity (constant variance of residuals)

    • Normality of residuals

    • No multicollinearity among independent variables

  • Answered by AI
  • Q2. What is the difference between R-Squared and Adjusted R-Squared?
  • Ans. 

    R-Squared measures the proportion of variance explained by the model, while Adjusted R-Squared adjusts for the number of predictors in the model.

    • R-Squared increases as more predictors are added to the model, even if they are not relevant.

    • Adjusted R-Squared penalizes for adding irrelevant predictors, making it a more reliable measure of model fit.

    • R-Squared can never decrease when adding predictors, while Adjusted R-Squa...

  • Answered by AI
  • Q3. What is Central Mean Theorem?
  • Ans. 

    Central Limit Theorem states that the sampling distribution of the sample mean approaches a normal distribution as the sample size increases.

    • The Central Limit Theorem is a fundamental concept in statistics that states that the sampling distribution of the sample mean will be approximately normally distributed, regardless of the shape of the population distribution, as the sample size increases.

    • It is important because i...

  • Q4. What is the difference between Rank and Dense Rank in SQL?
  • Ans. 

    Rank assigns unique ranks to each row based on the order specified, while Dense Rank assigns consecutive ranks without gaps.

    • Rank may have gaps in ranks if there are ties, while Dense Rank does not have gaps.

    • Rank function is used to assign a unique rank to each row based on the specified order, while Dense Rank function assigns consecutive ranks.

    • Example: If three rows have the same value and are ranked 1, 1, and 2 using...

  • Answered by AI
  • Q5. What is the difference between Series and Dataframe?
  • Ans. 

    Series is a one-dimensional labeled array while Dataframe is a two-dimensional labeled data structure.

    • Series can hold data of any type while Dataframe is a collection of Series.

    • Dataframe is like a table with rows and columns, while Series is like a single column of that table.

    • Dataframe is more versatile and powerful compared to Series.

    • Example: Series - a column of employee names. Dataframe - a table with columns for em

Round 3 - Technical 

(3 Questions)

  • Q1. Explain Random Forest algorithm
  • Ans. 

    Random Forest is an ensemble learning algorithm that creates multiple decision trees and combines their predictions.

    • Random Forest is a collection of decision trees that are trained on random subsets of the data.

    • Each tree in the Random Forest independently predicts the outcome, and the final prediction is made by averaging the predictions of all trees.

    • Random Forest is used for classification and regression tasks, and it...

  • Answered by AI
  • Q2. What is the difference between Stemming and Lemmatization? Which one is better and why?
  • Ans. 

    Stemming reduces words to their root form, while lemmatization reduces words to their dictionary form.

    • Stemming chops off prefixes or suffixes to get the root form (e.g. 'running' becomes 'run')

    • Lemmatization uses vocabulary analysis to reduce words to their base form (e.g. 'better' becomes 'good')

    • Lemmatization is more accurate but slower than stemming

    • Stemming is faster but may not always result in a valid word

  • Answered by AI
  • Q3. Questions about my previous projects
