The image contains a 4x5 grid of numbers. The numbers, arranged in rows from top to bottom, are as follows:

- Row 1: 72, 74, 71, 71, 76
- Row 2: 70, 77, 76, 72, 72
- Row 3: 77, 73, 75, 70, 73
- Row 4: 74, 75, 73, 74, 74

Each cell in the grid contains a two-digit number. The numbers appear to be arranged in separate columns and rows for organizational purposes, likely representing data such as scores or measurements. There are no graphs or diagrams accompanying the grid.
