  • Highly extensible through packages.
  • Data manipulation and cleaning.
  • Advanced data visualization (ggplot2 package).
• Example:

  # Calculate mean of a vector
  data <- c(1, 2, 3, 4, 5)
  mean(data)
  
  # Create a basic plot
  plot(data)
  

• Description: A versatile programming language with powerful libraries for data analysis and visualization.
• Features:
  • Data manipulation (Pandas).
  • Numerical computations (NumPy).
  • Data visualization (Matplotlib, Seaborn).
• Example:

  import pandas as pd
  import numpy as np
  import matplotlib.pyplot as plt
  
  # Create a DataFrame
  data = {'Age': [23, 45, 12, 36, 28]}
  df = pd.DataFrame(data)
  
  # Calculate mean age
  mean_age = df['Age'].mean()
  
  # Plot data
  plt.hist(df['Age'])
  plt.show()
  

• Description: A powerful data visualization tool that helps in creating interactive and shareable dashboards.
• Features:
  • Drag-and-drop interface.
  • Real-time data analysis.
  • Interactive dashboards.
  • Integration with various data sources.
• Example:
  • Connect to a data source (e.g., Excel, SQL database).
  • Drag fields to rows and columns to create visualizations.
  • Customize visualizations with filters and interactive elements.

Task: You have collected survey data on customer satisfaction. The data includes customer age, satisfaction rating (1-5), and comments. Use Excel to analyze this data.

Steps:

1. Organize Data: Enter the data into an Excel spreadsheet.
2. Calculate Descriptive Statistics:
   • Use AVERAGE to find the mean satisfaction rating.
   • Use STDEV to find the standard deviation of satisfaction ratings.
3. Create a Pivot Table:
   • Summarize satisfaction ratings by age group.
4. Visualize Data:
   • Create a bar chart to show the average satisfaction rating by age group.

Solution:

1. Organize Data:

   | Age | Satisfaction Rating | Comments           |
   |-----|---------------------|--------------------|
   | 25  | 4                   | Good service       |
   | 34  | 5                   | Excellent          |
   | 22  | 3                   | Average experience |
   | 45  | 4                   | Satisfied          |
   | 30  | 2                   | Needs improvement  |
   

2. Calculate Descriptive Statistics:

   =AVERAGE(B2:B6)  // Mean satisfaction rating
   =STDEV(B2:B6)    // Standard deviation of satisfaction ratings
   

3. Create a Pivot Table:

   • Select the data range.
   • Insert a Pivot Table.
   • Drag Age to Rows and Satisfaction Rating to Values.
   • Set the value field to show the average.

4. Visualize Data:

   • Select the Pivot Table.
   • Insert a bar chart.
