LESSON Reading Tables, Bar Charts, Pie Charts, Line Graphs Four ways the GRE packages data — and the one reading skill each one rewards: find the cell, compare the heights, follow the trend, read the slice. 1. Tables — Find the Intersection A table organizes exact values into rows and columns , and every table question is the same move: identify the row you need, identify the column you need, and read the single cell where they cross. Below is a company's revenue and profit (in millions of dollars) across three years. Watch the lookup find profit in 2022 — then pull a second cell from the same column to answer the actual GRE question: how much did profit grow from 2020 to 2022? profit growth, 2020 → 2022 — two cells from the same column 2. Bar Charts — Read the Height A bar chart trades exact table cells for a fast visual comparison: taller bar = bigger value . To read one precisely, don't eyeball it — trace a horizontal guide line from the bar's top over to the y-axis and read the number where it lands. Ranking categories is then nothing more than ranking the bars. Product C sold 70 units and Product A sold 40 — a difference of 70 - 40 = 30 units, and C outsold A by a factor of . Both readings come straight off the same two bar heights; the chart never asks you to guess, only to measure. 3. Line Graphs — Follow the Trend
