Title: Data Science Course (1)
1- 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
Reduction
2(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
