Example: A survey asked 100 people about their preferred mode of transport. The results are displayed in a bar chart:

Interpretation:

• Most Preferred Mode: The "Car" category has the tallest bar, indicating that most people prefer traveling by car.
• Least Preferred Mode: The "Train" category has the shortest bar, showing it is the least preferred.
• General Trend: Most people prefer personal transport (car), with public transport options being less popular.

Example: The heights of 30 students are measured, and the data is grouped into intervals:

Interpretation:

• Distribution Shape: The histogram is roughly symmetrical, indicating a normal distribution of heights.
• Central Tendency: Most students fall into the 160-164 cm interval, suggesting this is the most common height range.
• Spread: The range of heights is from 150 to 174 cm, showing moderate variability in student heights.

Example: A company's revenue is divided among four product categories:

Interpretation:

• Largest Sector: "Electronics" occupies the largest sector, contributing 40% of the total revenue.
• Smallest Sector: "Books" contribute only 10%, indicating this category is the least significant in terms of revenue.
• Proportional Comparison: Electronics generate twice as much revenue as Home Goods, highlighting their importance to the business.

Example: A company's monthly sales over a year are plotted on a line graph:

Interpretation:

• Overall Trend: The line graph shows a steady increase in sales over the year, indicating positive growth.
• Seasonal Trends: The steepest increase occurs towards the end of the year, possibly due to holiday sales.
• Forecasting: If the trend continues, sales are expected to keep increasing in the following year.

Example: A study examines the relationship between study hours and exam scores:

Interpretation:

• Positive Correlation: The points on the scatter plot rise from left to right, indicating a positive correlation between hours studied and exam scores.
• Strength of Relationship: The points are close to forming a straight line, suggesting a strong relationship between the variables.
• Outliers: If there were a point far away from the others (e.g., studying 10 hours but scoring 50), it would indicate an outlier, possibly due to other factors affecting the score.

Example: The test scores of students in two classes are compared using box plots:

Interpretation:

• Central Tendency: Class B has a higher median score (70) than Class A (65), indicating better overall performance.
• Spread: Class A has a wider interquartile range (IQR), suggesting greater variability in scores.
• Outliers: Check for any points outside the whiskers; these would indicate outliers.
