  • Exploratory Data Analysis (EDA) Unveiling
    Insights
  • Data Profiling and Summary Statistics
  • Start by conducting data profiling to understand
    the structure and characteristics of the
    dataset. Data Science Course. Compute summary
    statistics such as mean, median, standard
    deviation, and quartiles for numerical variables,
    and frequency distributions for categorical
    variables. This initial exploration provides
    insights into the data's distribution, central
    tendencies, and variability.
  • Visualization Techniques
  • Utilize a variety of visualization techniques to
    explore the relationships and patterns within
    the dataset. Create histograms, box plots, and
    density plots to visualize the distribution of
    numerical variables. Use bar charts, pie charts,
    and heat maps to analyze categorical variables
    and their relationships. Scatter plots and pair
    plots can reveal correlations and associations
    between variables.
  • Handling Missing Values and Outliers
  • Identify and handle missing values and outliers
    in the dataset. Visualize missing data patterns
    using heatmaps or bar plots to understand the
    extent of missingness across variables. Employ
    techniques such as imputation, deletion, or
    advanced methods like predictive modeling to
    handle missing values. Use box plots, scatter
    plots, or z-score analysis to detect and address
    outliers appropriately.
  • Feature Engineering and Transformation
  • Explore feature engineering techniques to derive
    new variables or transform existing ones. Create
    new features by combining or aggregating existing
    variables to capture meaningful patterns in the
    data. Perform transformations such as logarithmic
    or polynomial transformations to normalize
    skewed distributions and improve model
    performance.
  • Correlation Analysis and Dimensionality

(PCA) or t-distributed stochastic neighbor
embedding (t-SNE) to visualize high-dimensional
data and uncover underlying structures. By
incorporating these pointers into exploratory
data analysis, analysts can gain valuable
insights into the dataset's characteristics,
relationships, and patterns. Data Science Course
in Mumbai. EDA serves as a crucial step in the
data analysis process, enabling analysts to make
informed decisions, identify potential issues,
and formulate hypotheses for further
investigation. Business name ExcelR- Data
