Data Science
● “…a ﬁeld that deals with unstructured, structured data, and semi-structured
data. It involves practices like data cleansing, data preparation, data analysis,
and much more.
● Data science is the combination of statistics, mathematics, programming, and
problem-solving; capturing data in ingenious ways; the ability to look at things
differently; and the activity of cleansing, preparing, and aligning data.”

Data Science Road Map
● Descriptive Statistics
● Probability
● Python (OOP + Pandas + Numpy + Scipy)
● Data Cleaning: One of the MOST important skills that you need to master to
become a good data scientist, you need to practice on many datasets to
master it.
● Data Visualization (using Matplotlib and seaborn )
● Dashboards (Tableau)
● SQL and DB (SQL for Data Analysis)
● Time Series Analysis

Descriptive Statistics
It is used to summarize the main features of a data set, such as its central tendency, variability,
and distribution. Descriptive statistics can be used to describe a data set in a way that is easy
to understand and interpret. Some of the most common descriptive statistics include:
● Mean: The mean is the average of all the values in a data set.
● Median: The median is the middle value in a data set when all the values are arranged in
order from least to greatest.
● Mode: The mode is the most frequent value in a data set.
● Range: The range is the difference between the largest and smallest values in a data set.
● Variance: The variance measures how spread out the values in a data set are.
● Standard deviation: The standard deviation is a measure of how much variation there is
from the mean in a data set.

Probability
● Model uncertainty: Data is often noisy and incomplete, which means that there is
uncertainty about the true values of the data. Probability can be used to model this
uncertainty and to make inferences about the data.
● Make predictions: Probability can be used to make predictions about future events, given
the observed data. For example, a data scientist might use probability to predict the
likelihood of a customer clicking on an ad, or the likelihood of a patient recovering from a
disease.
● Detect anomalies: Probability can be used to detect anomalies in data. An anomaly is an
observation that is signiﬁcantly different from the rest of the data. Probability can be used
to identify anomalies by calculating the likelihood of an observation occurring.
● Cluster data: Probability can be used to cluster data into groups of similar observations.
This can be useful for identifying patterns in the data and for making predictions about

Python Libraries (Pandas ,Numpy , Scipy )
Pandas is a Python library that provides high-performance, easy-to-use data structures and data
analysis tools. It is widely used by data scientists for data manipulation, analysis, and
visualization.
NumPy is a Python library that provides a high-performance multidimensional array object, along
with a suite of functions for working with arrays. It is used in a wide variety of domains, including
scientific computing, data science, and machine learning.
SciPy is a scientific computation library that uses NumPy underneath. SciPy stands for Scientific
Python. It provides more utility functions for optimization, stats and signal processing.

Data Cleaning
● Identifying and correcting errors: This includes fixing typos, correcting incorrect values,
and removing duplicate data.
● Imputing missing values: This involves filling in missing data with either estimated values
or by removing the rows or columns with missing data.
● Dealing with outliers: Outliers are data points that are significantly different from the rest
of the data. They can be caused by errors or by unusual circumstances. Outliers can be
removed, or they can be treated as separate categories.
● Data formatting: This involves converting the data into a format that is easy to use and
analyze. This can involve changing the data type, or converting it into a different file
format.
● Data normalization: This involves scaling the data so that all of the values are within a
similar range. This can make it easier to compare the data and to identify trends.

Data Visualization Libraries
● Matplotlib and Seaborn are two popular Python libraries for data visualization. Matplotlib is a
general-purpose library that can be used to create a variety of charts and graphs. Seaborn is built on
top of Matplotlib and provides a number of high-level functions for creating statistical plots.
● Creating bar charts: Bar charts are used to show the distribution of data. They can be used to show
the number of observations in each category, or the average value of a variable in each category.
● Creating line charts: Line charts are used to show the trend of data over time. They can be used to
show how a variable changes over time, or how two variables are related to each other.
● Creating scatter plots: Scatter plots are used to show the relationship between two variables. They
can be used to show how two variables are correlated, or to identify outliers.
● Creating histograms: Histograms are used to show the distribution of data. They can be used to show
the number of observations in each range of values, or the probability of a value occurring.
● Creating box plots: Box plots are used to show the distribution of data. They can be used to show the
median, quartiles, and outliers of a data set.

Dashboards - Tableau
A dashboard is a visual representation of data that helps users to monitor and analyze
information. Dashboards are typically used in business settings to track performance, identify
trends, and make decisions.
Tableau is a business intelligence (BI) tool that allows
users to create interactive dashboards.
Tableau is a popular choice for dashboard creation
because it is easy to use and has a wide range of
features.

SQL & DB
It helps data scientists access, manage, and analyze large data sets to derive
insights that can drive better business decisions.
For professionals looking to build a career in data science, learning SQL is a
must-have skill

Time Series Analysis
● Time series analysis is a statistical technique that is used to analyze data that is
collected over time. It is used to identify patterns and trends in the data, and to
make predictions about future values.
● Forecasting: Time series analysis can be used to forecast future values of a
variable. This can be useful for making business decisions, such as setting prices
or planning production.
● Identifying trends: Time series analysis can be used to identify trends in the data.
This can be useful for understanding the behavior of the variable and for making
predictions about future values.
