Question: What is Data Analytics?
Answer: Data Analytics is the process of examining, cleaning, transforming, and modeling data to discover useful information, draw conclusions, and support decision-making.

Question: Differentiate between Descriptive and Predictive Analytics?
Answer: Descriptive Analytics summarises historical data, while Predictive Analytics predicts future outcomes based on historical data patterns.

Question: Explain the term “Big Data.”
Answer: Big Data refers to extremely large and complex datasets that traditional data processing methods struggle to handle. It involves high volume, velocity, and variety of data.

Question: What is the purpose of exploratory data analysis (EDA)?
Answer: EDA is used to analyze and summarize the main characteristics of a dataset, often with the help of graphical representations, to understand the patterns and relationships within the data.

Question: Define the term “Data Mining.”?
Answer: Data Mining is the process of discovering patterns, trends, and useful information from large datasets using various techniques, including machine learning and statistical methods.

Question: What is the significance of the Central Limit Theorem in statistics?
Answer: The Central Limit Theorem states that, regardless of the distribution of the population, the sampling distribution of the mean will be approximately normally distributed if the sample size is large enough. This is fundamental for statistical inference.

Question: Explain the concept of correlation.
Answer: Correlation measures the statistical association between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect positive correlation, and 0 indicates no correlation.

Question: What is the difference between data cleaning and data preprocessing?
Answer: Data cleaning involves identifying and correcting errors or inconsistencies in the dataset, while data preprocessing includes tasks such as normalization, transformation, and handling missing values to prepare the data for analysis.

Question: Define outlier in the context of data analysis.
Answer: An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. It may indicate a data entry error or a significant deviation from the overall pattern.

Question: Explain the terms “precision” and “recall” in the context of classification models.
Answer: Precision is the ratio of correctly predicted positive observations to the total predicted positives, while recall is the ratio of correctly predicted positive observations to all the actual positives.

Question: What is the purpose of a box plot in data visualization?
Answer: A box plot provides a visual summary of the distribution of a dataset, showing the median, quartiles, and potential outliers. It is useful for identifying the spread and central tendency of the data.

Question: Differentiate between supervised and unsupervised learning.
Answer: In supervised learning, the algorithm is trained on a labelled dataset, where the output is known. In unsupervised learning, the algorithm explores the data without explicit guidance and discovers patterns or relationships.

Question: What is the difference between a bar chart and a histogram?
Answer: A bar chart is used to display categorical data, while a histogram represents the distribution of a continuous variable by dividing it into intervals (bins) and counting the frequency in each bin.

Question: What is the role of a decision tree in machine learning?
Answer: A decision tree is a predictive model that maps features to outcomes. It is used for classification and regression tasks, making decisions based on the values of input features.

Question: Define the term “p-value” in statistical hypothesis testing.
Answer: The p-value is the probability of obtaining results as extreme as the observed results of a statistical hypothesis test, assuming that the null hypothesis is true. A smaller p-value suggests stronger evidence against the null hypothesis.

Question: Explain the concept of dimensionality reduction in data analysis.
Answer: Dimensionality reduction involves reducing the number of features or variables in a dataset. It is done to simplify the model, improve computational efficiency, and eliminate redundant information.

Question: What is a time series analysis, and when is it used?
Answer: Time series analysis involves studying the patterns and trends in data collected over time. It is used to make predictions, identify seasonality, and understand the temporal behavior of a variable.

Question: Define the term “confusion matrix” in the context of classification models.
Answer: A confusion matrix is a table used to evaluate the performance of a classification model. It shows the true positive, true negative, false positive, and false negative values, enabling the calculation of various performance metrics.

Question: Explain the concept of cross-validation in machine learning.
Answer: Cross-validation is a technique used to assess the performance of a machine learning model by splitting the dataset into multiple subsets. It helps ensure that the model generalizes well to unseen data.

Question: What is the purpose of a scatter plot in data visualization?
Answer: A scatter plot is used to visualize the relationship between two continuous variables. It helps identify patterns, correlations, and outliers in the data.

Question: Define the term “data warehouse” in the context of data management.
Answer: A data warehouse is a centralized repository that stores and manages large volumes of data from various sources. It is designed for querying and reporting, supporting decision-making processes.

Question: What is the difference between correlation and causation?
Answer: Correlation indicates a statistical association between two variables, while causation implies that one variable directly influences the other. Correlation does not imply causation.

Question: Explain the concept of data normalization.
Answer: Data normalization is the process of scaling and centring numerical features, ensuring that they have a consistent scale. It helps prevent certain features from dominating others in machine learning models.

Question: What is the purpose of a pie chart in data visualization?
Answer: A pie chart is used to represent the proportions of different categories in a dataset. It is particularly useful for illustrating the composition of a whole in terms of percentages.

Question: Define the term “resampling” in the context of data analysis.
Answer: Resampling involves creating new samples from the existing data to assess the robustness and stability of statistical estimates. It is commonly used in bootstrapping and cross-validation techniques.
