Explore in-depth sampling methods, define population, sample, census, and survey, and demonstrate random, stratified, and cluster sampling in Excel and Python.
Explore basic statistics terminology, including population and sample, data collection methods like Sensex and survey, and how samples enable inference about the population.
Explore data collection techniques by examining convenient sampling, a non-probability method, and random sampling, a probability-based method, with examples like exit polls and online surveys.
Explore four random sampling techniques—random sampling, systematic random sampling, stratified random sampling, and cluster random sampling—and learn how each method selects samples from a population.
Learn convenient sampling in Excel by selecting five favorite customers from a data file, illustrating bias in sample selection and planning to extend to Python later.
Use Excel to perform random sampling by generating uniform random numbers, paste values to fix them, sort by these numbers, and select five random customers from the data.
Learn to perform random sampling in Excel using the Analysis ToolPak. Install the add-in, access data analysis, and run random or systematic sampling.
Demonstrates how to perform systematic random sampling in Excel by sorting by customer ID, selecting every fourth record, and using the Data Analysis Toolpak to verify results.
Learn how to perform stratified random sampling by country in Excel, generating random numbers, ranking within each strata, and selecting one customer from every country for unbiased samples.
Perform cluster sampling by selecting a random country from the unique countries and collecting all customers from that country in Excel using random between, country IDs, and filters.
Load the customer_country.xlsx dataset in Python using pandas read_excel in a Jupyter notebook to practice sampling techniques.
Explore random sampling in Python with pandas by using df.sample(n=5) to select five random customers and display only their customer_id.
Learn how to perform systematic random sampling by selecting every fourth customer after sorting by customer ID, resetting the index, and extracting the corresponding customer IDs using NumPy arange.
Master stratified random sampling by grouping data by country, shuffling, and selecting samples from each country using three methods in pandas: groupby with sample, lambda application, and fraction-based sampling.
Explore cluster random sampling by selecting one country at random and drawing all customers from that country, using pandas data frames, unique country extraction, and query filtering.
Unlock the power of Business Statistics by mastering sampling techniques with Python and Excel! This course provides a practical, hands-on approach to understanding statistics and its applications in real-world data analysis.
What You’ll Learn:
Introduction to Statistics – Understand key statistical concepts and why sampling is crucial for data-driven decision-making.
Types of Sampling Methods:
Convenience Sampling – Quick and easy data collection.
Simple Random Sampling – Every data point has an equal chance of being selected.
Systematic Sampling – Selecting every ‘nth’ data point from a dataset.
Stratified Sampling – Dividing data into meaningful subgroups before sampling.
Cluster Random Sampling – Random selection of entire groups instead of individuals.
Key Highlights:
Hands-on Implementation in Python – Apply each sampling method using pandas and NumPy for real-world datasets.
Sampling in Excel – Learn how to generate and analyze samples using Excel’s built-in statistical tools.
