How to Prepare Histogram in Excel?
Example-1:
A Process engineer of an organization (XYZ Ltd) had decided to know the bins range [frequency distribution] of pouring temperature of casting and he has started collecting the data of 30 number readings and analyzing that data distribution that histogram graph is normal or non-normal. Illustrations of the same readings are given below,

| Parameter: | Pouring Temperature of Casting | 1390±10°C | M/C | Shift | Date |
| Sl. No | Readings | Sl. No | Readings |
| 1 | 1390 | 16 | 1399 |
| 2 | 1389 | 17 | 1395 |
| 3 | 1395 | 18 | 1397 |
| 4 | 1394 | 19 | 1396 |
| 5 | 1393 | 20 | 1392 |
| 6 | 1392 | 21 | 1393 |
| 7 | 1397 | 22 | 1393 |
| 8 | 1398 | 23 | 1400 |
| 9 | 1397 | 24 | 1389 |
| 10 | 1393 | 25 | 1390 |
| 11 | 1396 | 26 | 1390 |
| 12 | 1400 | 27 | 1391 |
| 13 | 1391 | 28 | 1392 |
| 14 | 1400 | 29 | 1393 |
| 15 | 1398 | 30 | 1397 |
| Min. | 1389 |
| Max. | 1400 |
| Count | 30 |
| Interval | 1.2 |
| Parameter | Frequency |
| 1389 | 2 |
| 1390.2 | 3 |
| 1391.4 | 2 |
| 1392.7 | 3 |
| 1393.9 | 5 |
| 1395.1 | 3 |
| 1396.3 | 2 |
| 1397.6 | 4 |
| 1398.8 | 2 |
| 1400.0 | 1 |
| 1401.2 | 3 |
| Sum of frequency | 30 |
Interpretation of Result: Non-normal data distribution.
Example-2:
We have collected the 30 readings of green sand permeability, details are given below and also, and we have plotted a histogram to know the data frequency distribution.
