Read values from a table or chart.

SECTION 1

Historical Context & Motivation

Long ago, people needed a way to organize lots of numbers so they could understand them quickly. Tables and charts (also called graphs) were invented to solve this problem. They turn messy data into something easy to read, like a neat scoreboard at your favorite game.

1786

First Charts

William Playfair creates the first bar chart and line chart to show trade data.

1858

Nightingale's Diagram

Florence Nightingale uses a special chart to prove hospitals needed better care. Her work saves lives!

1920

Pie Charts Appear

Pie charts become popular for showing parts of a whole, like slices of pizza.

1985

Computer Graphs

Computers make charts easy to create on programs like Excel.

Today on the SSAT, you will see tables and charts with sports scores, animal populations, or store sales. Learning to read them quickly gives you a big advantage!

SECTION 2

Core Principles of Tables and Charts

A table organizes data in rows and columns, like a grid on graph paper. A chart (or graph) uses pictures like bars or lines to show the same data visually.

Read the Title First

It tells what the data is about, like 'Fruit Sales Last Week'.

Check Labels and Units

Labels name categories. Units like dollars ($) or people show measurements.

Find the Value

Match row and column in tables, or read height/length in charts.

Compare Carefully

Look side-by-side to see which is bigger or by how much.

⚾ Quick Tip

Reading a chart is like checking the scoreboard during a baseball game. You quickly spot your team's runs without counting every player!

SECTION 3

Visualizing a Bar Chart

The bars show sales: apples tallest at 80, then bananas at 60, oranges shortest at 40. Units are number sold.

See how the bar for apples goes highest? That means most apples sold. Always check the side scale to read exact numbers.

SECTION 4

Step-by-Step: How to Read Values

Start with the title to understand the topic.
Look at row and column labels in tables or axis labels in charts.
Note the units like kg or %.
Trace to find the exact value and compare if needed.

✦ KEY TAKEAWAY

You are like a detective hunting clues in the labels. Find your answer fast!

SECTION 5

Common Tables and Charts on SSAT

Table example: Find Alex's Math score by matching row 'Alex' and column 'Math' at 85.

Tables use rows for one category and columns for another. Charts like bars show the same info with pictures for quick spotting of biggest/smallest.

SECTION 6

Worked Example: Reading a Table

Suppose a table shows dog ages and weights:

Dog Weights Table

Dog	Age (years)	Weight (lbs)
Max	3	25
Bella	5	40
Rex	2	30

Question: How much heavier is Bella than Max?

Step 1: Find Bella's weightRow 'Bella', column 'Weight (lbs)': 40 lbs.

Step 2: Find Max's weightRow 'Max', column 'Weight (lbs)': 25 lbs.

Step 3: Subtract40 − 25 = 15 lbs heavier.

SECTION 7

Strengths of Tables vs. Charts

Type	Strength	Best For
Table	Exact numbers easy to find.	Precise math like totals.
Chart	Quick trends and compares.	Seeing biggest/smallest fast.

⭐ KEY TAKEAWAY

Use tables for math, charts for patterns — you pick the right tool every time!

SECTION 8

From Basic to Advanced

Basic	Advanced	What's New
Bar chart	Scatter plot	Shows patterns between two changing things.
Simple table	Line graph	Tracks changes over time.

SSAT sticks to basics, but knowing advanced helps you feel ready for more. Practice now to shine!

SUMMARY

Quick Review

Always check title, labels, units first in tables and charts. Trace rows/columns or read bar heights for values.
