Data Science Interview Questions

What do you infer from logistic regression?

Logistic regression is a statistical model which utilises logistic function for modelling dependent variables which are binary in nature. Logistic regression is deployed for the prediction of binary outcome from any linear combination for the predictor variables.

Define Selection Bias.

Selection bias describes a situation where the sample analyzed differs from the whole set of data in important aspects for which they are analyzed, resulting in biased conclusions. This is a type of error, which occurs during the decision process. It is also known as the Selection effect.

The various kinds of selection bias consists of:

Sampling bias- This occurs when the samples present in a population are non-random.

Time interval- The termination of the trial occurs at an early stage for extreme value.

Data- When particular data subsets are selected for the supporting of conclusion over arbitrary grounds.

Attrition- It is also a type of selection bias that is caused due to attrition.

How is data cleaning important in analysis?

For each data analysis process, data cleansing is very important though it may consume more time. Also, data is accumulated from various sources to convert the whole dataset into a specific format, which can be processed by the data scientists. There might be data that are duplicate, redundant and unworthy to the analysis being carried out.

What do you infer from Normal distribution?

Normal Distribution, also known as Gaussian distribution is a distribution in probability where the data is spread symmetrically about the mean, which implies that Data closer to the mean occurs more frequently than the data farther from the mean. Data is distributed about the central value irrespective of its reach that may occur in the form of a bell curve.

Characteristics of normal distribution are:

  • Unimodal
  • Bell
  • Symmetrical
  • Asymptotic
  • Mean, median and mode

Differentiate between Systematic and Cluster sampling.

The major difference between Systematic and Cluster sampling is the manner in which they pick sample from the population.

Systematic Sampling Cluster Sampling
Here, Sample is picked from the population from any random starting point and at regular intervals from the starting point depending on the size of the population. In Cluster Sampling, the population is divided into clusters and a random sample is taken from each cluster.
Provide accurate results Results are less accurate compared to systematic sampling
Probability sampling method Random sampling method
This is used when the population contains important units throughout and while making important decisions based on the sampling. This can be used when the population is large and it reduces the time and money spent.

Point out the difference between underfitting and overfitting.

Both of these terms denote the state of the statistical models or machine learning algorithms which hampers reliable predictions from the generated data.

When we consider overfitting, the statistical model characterizes noise or inaccurate data rather than the underlying relationship. Here, the model is fed with tons of data exceeding the capacity of the model. Its usage is visualized when there is a presence of a complex model that comprises of many parameters related to the counting of observations.

The Underfitting process occurs when any statistical model is unable to grasp the fundamental trend of data. This happens when there is insufficient data for building an accurate model.

How is Supervised learning different from unsupervised learning?

Supervised learning is a process in which an algorithm is learned from the training dataset. Here we use an algorithm to map the input and output using the available input/output variables in the training dataset. This mapping enables to predict outcome variables when new input data is fed.

In Unsupervised learning, there is no training dataset and we only have input data that contains hidden patterns and distributions of data. It aims at modeling the hidden patterns in the data to understand more about the data.

Data scientists predominantly use both types of learning where unsupervised learning is used to process the data during exploratory analysis and to train supervised learning algorithms using the generated data set from unsupervised learning. Supervised learning is used for financial analysis, training neural networks,  forecasting, facial recognition, and various other processes.

Explain univariate, bivariate and multivariate analysis.

Univariate analysis is considered to be the simplest form of statistical analysis, which utilizes only one variable data set. It is used to describe, summarise and find patterns in the Data.

Bivariate analysis tries to build a relationship between the available two-variable data sets.

Multivariate Analysis deals with acquiring knowledge of multiple variables to understand the aftermath of the presence of variables over the responses.

What do you mean by box cox transformation in the regression model?

The response variable involved in regression analysis may not satisfy numerous assumptions of any ordinary square regression. A Box-Cox transformation helps to convert non-normal dependent variables into a normal shape. If the data is abnormal, applying Box-Cox transformation can help to run a wide range of tests as normality is an important criterion for many statistical techniques.

What do you infer from Eigen  vectors and Eigen  values?

The Eigenvectors are widely used for the understanding of linear transformation. The user calculates Eigenvectors for the covariance matrix during the data analysis. They are considered to be the directions for a specific linear transformation by the act of flipping, stretching or compressing.

The eigenvalue is known as strength for the change in direction of Eigenvector.

Data Science Tutorial

List few assumptions related with linear regression.

The presumptions regarding linear regression are mentioned below:

  • The relationship that persists amidst dependent variables and regressors is considered to fit the data that has been actually created by the user.
  • The distribution of error happens to be normal as well as being independent.
  • The multiple correlation is very minimum amidst the variables.
  • Variance all around regression line is identical for every predictor variable.

What do you infer from exploding gradients?

They are a sort of error gradients that gets accumulated while training a neural network algorithm resulting in huge updates for the neural network. This accumulation causes the neural network weights to increase abnormally during the process of training thus providing results in NaN values.

Gradients are used to train and update the network weights, which is beneficial when the gradients are small and controlled. If the magnitude of the error gradient accumulates it causes instability in the neural network algorithms spoiling the purpose of training.

What do you infer from SVM machine learning algorithm?

Support Vector Machine(SVM) can be deployed for  Classification and Regression. SVM attempts to find a hyperplane (in N-dimension space) that can classify every single feature with specific coordinates. This also makes use of hyperplanes to separate various classes based on the kernel function. A hyperplane is just a boundary between two or more classes of data.

How will be statistics used by Data scientists?

Statistics is the real soul of Data Science. Statistics is the most important subject that provides the tools and techniques to structurize data and find deeper insights from data. Its main usage will be seen in identifying the patterns and conversion of raw data to business insights. This also aids the data scientists to develop excellent ideas that are expected by the customers. It is easier for them to analyze the interest, consumer behavior, engagement, retention along with the perspective statistics. This also helps in building up of data models for the validation of certain interferences. Every aspect is possible to be converted to any business proposition.

What do you mean by Random Forest? And explain its working?

It is a flexible method deployed in machine learning to perform classification and regression tasks. It is used in dimensionality reduction, outlier values, and treats missing values. This is considered to be a kind of ensemble in which weak models are combined to create a powerful model.

It is possible to grow several trees against any single tree for the classification of new objects that are based on attributes.

What do you mean by Extrapolation and Interpolation?

Both of these terms are considered very important in statistical analysis. Extrapolation is done to estimate value by extending a known sequence of values beyond the known area to infer implicit information from the provided information.

Interpolation is something used for the determination of specific value that lies amidst fixed values that is useful when there are two extremities of a specific region.

Differentiate between Data modelling and Database design.

Data modeling is the initial step in the process of Database design. This helps in the creation of a conceptual model that is based on connection amidst different data models. It consists of the transition of the conceptual stage to a logical model.

Database design is deployed for the plotting of a database that aids in the creation of  a precise data model. This consists of physical design choices along with storage parameters.

 List some of the disadvantages of linear model.

The most important drawbacks of this model are:

  • The expectation of linearity errors.
  • Outcomes count cannot be calculated.
  • Overfitting problems that are impossible to resolve.

When partial data is given by the user in any search engine, how is it possible to predict the search?

It can be predicted by the previous frequencies of various word sequence, conditional probabilities can be constructed for the next sequences, which can be shown up. The order that consists of the highest conditional probabilities will be shown on top of the suggestions list. For the additional improvisation of the mentioned algorithm, the user can add weight over the past series that appeared in the recent time.

  What do you infer from Boosting ?

This is an ensemble methodology for attempting in the creation of a strong classifier with the help of numerous weak classifiers primarily to reduce bias and variance. The performance of every tree is used for weighing how much attention is to be given to every next tree that is built-up. Every model is created in a follow-up manner, further updating weights.

What are all the pre-processing steps that are highly recommended?

List the pre-processing stages which are recommended.

  • Missing value treatments
  • Outlier Analysis
  • Feature engineering
  • Structural Analysis
