πŸ“Š Introduction to Statistics in Data Science: A Complete Beginner’s Guide

Statistics is the backbone of Data Science.

From understanding raw data to building predictive models, statistics helps data scientists make sense of uncertainty, patterns, and trends hidden inside data.

In this detailed guide, you’ll learn:

  • What statistics is (in simple terms)
  • Why statistics is critical for data science
  • Key statistical concepts every data scientist must know
  • Difference between statistics, mathematics, and machine learning
  • Real-world applications of statistics in data science

statistics for data science


πŸ“Œ What is Statistics?

Statistics is the science of collecting, analyzing, interpreting, and presenting data.

In simple words:

Statistics helps us turn raw data into meaningful insights.

Example:

If a company collects sales data from 10,000 customers, statistics helps answer:

  • What is the average purchase value?
  • Which product sells the most?
  • Is sales increasing or decreasing over time?

Without statistics, data is just numbers with no meaning.


πŸ“Œ Why Statistics is the Backbone of Data Science

Data Science is not just about coding or machine learning.
At its core, it is about decision-making using data, and statistics provides the foundation for that.

Why statistics is essential in data science:

1️⃣ Understanding Data

Before applying any machine learning algorithm, a data scientist must:

  • Understand data distribution
  • Detect outliers
  • Identify missing values
  • Summarize data using statistical measures

2️⃣ Making Inferences from Data

Statistics helps answer questions like:

  • Is this result significant or just random?
  • Can we generalize sample results to the population?
  • How confident are we in our predictions?

3️⃣ Model Evaluation

Statistical concepts are used to:

  • Measure model accuracy
  • Compare multiple models
  • Validate assumptions
  • Avoid overfitting

4️⃣ Decision Making Under Uncertainty

Real-world data is noisy and imperfect.
Statistics allows data scientists to quantify uncertainty and make informed decisions.


πŸ“Œ Key Statistical Concepts Used in Data Science

πŸ”Ή 1. Descriptive Statistics

Descriptive statistics summarize and describe data.

Common measures include:

  • Mean (Average)
  • Median
  • Mode
  • Variance
  • Standard Deviation
  • Percentiles

πŸ“Š Example:
Average salary of employees, highest score in an exam, monthly revenue summary.


πŸ”Ή 2. Probability

Probability measures the likelihood of an event occurring.

Why probability matters in data science:

  • Used in predictive modeling
  • Foundation of machine learning algorithms
  • Helps estimate risk and uncertainty

πŸ“Œ Example:

What is the probability that a customer will churn next month?


πŸ”Ή 3. Inferential Statistics

Inferential statistics allows us to draw conclusions about a population using a sample.

Key techniques:

  • Confidence Intervals
  • Hypothesis Testing
  • Statistical Significance

πŸ“Œ Example:

Can we conclude that a new marketing strategy increased sales?


πŸ”Ή 4. Data Distributions

Understanding how data is distributed is crucial.

Common distributions:

  • Normal Distribution
  • Binomial Distribution
  • Poisson Distribution

πŸ“Š Many ML algorithms assume data follows a normal distribution.


πŸ”Ή 5. Correlation and Regression

These techniques help understand relationships between variables.

  • Correlation: Measures strength of relationship
  • Regression: Predicts one variable using others

πŸ“Œ Example:

How does advertising spend affect sales?


πŸ“Œ Statistics vs Mathematics vs Machine Learning

AspectStatisticsMathematicsMachine Learning
PurposeAnalyze & interpret dataAbstract problem solvingLearn patterns from data
FocusUncertainty & inferenceTheory & proofsPrediction & automation
DataReal-world dataOften theoreticalLarge datasets
OutputInsights & decisionsEquationsModels & predictions

πŸ‘‰ Statistics bridges mathematics and machine learning.


πŸ“Œ Real-World Use Cases of Statistics in Data Science

🏦 1. Business & Marketing

  • Customer segmentation
  • A/B testing
  • Demand forecasting
  • Pricing optimization

πŸ’° 2. Finance

  • Risk analysis
  • Fraud detection
  • Portfolio optimization
  • Credit scoring

πŸ₯ 3. Healthcare

  • Clinical trials
  • Disease prediction
  • Treatment effectiveness analysis

πŸ›’ 4. E-Commerce

  • Recommendation systems
  • Conversion rate optimization
  • Customer churn analysis

πŸ“± 5. Technology & AI

  • Model evaluation
  • Feature selection
  • Performance metrics


πŸ“Œ Simple Example Using Python

import numpy as np data = [50, 60, 70, 80, 90] mean = np.mean(data) std_dev = np.std(data) print("Mean:", mean) print("Standard Deviation:", std_dev)

πŸ“Œ This basic statistical analysis helps understand data spread before modeling.


πŸ“Œ Why Data Scientists Must Learn Statistics First

Many beginners jump directly into machine learning, but without statistics:

  • Models become black boxes
  • Results are misinterpreted
  • Decisions become risky

πŸ‘‰ Strong statistics = strong data scientist


πŸ“Œ Final Thoughts

Statistics is not optional in data science β€” it is foundational.

Whether you’re analyzing customer data, building predictive models, or evaluating AI systems, statistics ensures your insights are accurate, reliable, and meaningful.

In the next post of this series, we’ll dive deeper into Types of Data and Measurement Scales in Statistics.

πŸ“† SAS Date Interval Functions Explained: INTNX vs INTCK with Examples

Date manipulation is a core part of data analysis in SAS. When working with time series, financial models, or scheduling, calculating intervals and moving dates is essential. That’s where SAS functions like INTNX and INTCK come in.

SAS Date Functions - INTNX and INTCK

In this blog post, we will explore:

  • What are INTNX and INTCK functions?
  • Complete syntax and arguments
  • Important options
  • Practical real-life examples
  • Comparison and use-cases

πŸ” What is INTNX in SAS?

The INTNX (Interval Next) function adds a specified number of intervals to a date or datetime and returns a new date.

πŸ“Œ Syntax:

INTNX(interval, start-from, increment <, 'alignment' <, method>>)

βœ… Arguments:

ParameterDescription
intervalThe type of interval to add (e.g., day, week, month, year).
start-fromThe base SAS date or datetime value.
incrementNumber of intervals to move forward or backward.
'alignment' (optional)'BEGINNING', 'MIDDLE', 'END', 'SAME' (default is 'BEGINNING').
method (optional)'S' (simple), 'C' (concurrent), or 'E' (end of period alignment).

πŸ§ͺ INTNX Examples

Example 1: Add 3 months to a date

data result;
new_date = intnx('month', '01JAN2024'd, 3); format new_date date9.; run;

Output: 01APR2024


Example 2: Move 2 years back and align to end of year

data result;
year_end = intnx('year', '15JUL2024'd, -2, 'END'); format year_end date9.; run;

Output: 31DEC2022


Example 3: Use 'SAME' alignment

data result;
same_date = intnx('month', '10JAN2024'd, 1, 'SAME'); format same_date date9.; run;

Output: 10FEB2024


🧠 Pro Tip:

You can use INTNX with time intervals too, like 'hour', 'minute', 'qtr', 'dtday', etc.


⏳ What is INTCK in SAS?

The INTCK (Interval Check) function calculates the number of intervals between two dates or datetimes.

πŸ“Œ Syntax:

INTCK(interval, start, end <, 'method'>)

βœ… Arguments:

ParameterDescription
intervalType of interval (e.g., day, week, month, year).
startStarting SAS date or datetime.
endEnding SAS date or datetime.
'method' (optional)'C' (continuous), 'D' (discrete), or 'S' (simple)

πŸ§ͺ INTCK Examples

Example 1: Count number of months between two dates

data result;
month_diff = intck('month', '01JAN2023'd, '01JUL2023'd); run;

Output: 6


Example 2: Days between two dates

data result;
day_diff = intck('day', '15MAR2023'd, '20APR2023'd); run;

Output: 36


Example 3: Count number of years using 'CONTINUOUS' method

data result;
year_cont = intck('year', '31DEC2019'd, '01JAN2021'd, 'C'); run;

Output: 2
