Certainly! To draw a histogram for the daily earnings of 30 drug stores, follow these steps:
### Step-by-Step Solution:
1. Organize the Data:
We have the following data about the daily earnings of 30 drug stores:
- ₹100-150: 14 stores
- ₹200-250: 9 stores
- ₹250-300: 3 stores
- ₹300-350: 4 stores
2. Create the Blueprint for the Histogram:
A histogram is a type of bar chart representing the frequency of data points within certain ranges (bins). The x-axis will represent the range of daily earnings, and the y-axis will represent the number of stores.
3. Label the Axes:
- The x-axis should be labeled as "Daily earnings (in ₹)".
- The y-axis should be labeled as "Number of stores".
4. Draw the Bars:
Each bar corresponds to a range of daily earnings (also called bins) and their height corresponds to the number of stores that fall into that range.
- For the earnings range ₹100-150, draw a bar up to 14 (since 14 stores earn in this range).
- For the earnings range ₹200-250, draw a bar up to 9.
- For the earnings range ₹250-300, draw a bar up to 3.
- For the earnings range ₹300-350, draw a bar up to 4.
5. Add Titles and Labels:
- Add a title at the top of the histogram: "Histogram of Daily Earnings for 30 Drug Stores".
- Label the x-axis and y-axis as described earlier.
### Example Histogram:
Below is a representation of how the histogram should look:
```
Number of Stores

| _______

|__|_______|_________|_|___|____________________> Daily earnings (in ₹)
100-150 200-250 250-300 300-350
```
Here's a more detailed breakdown:
- The first bar (100-150) reaches up to 14 on the y-axis.
- The second bar (200-250) reaches up to 9 on the y-axis.
- The third bar (250-300) reaches up to 3 on the y-axis.
- The fourth bar (300-350) reaches up to 4 on the y-axis.
### Final Thoughts:
Ensure the bars are properly drawn to scale and the spaces between non-continuous categories (gaps) represent the actual gaps in the earnings ranges (as seen between ₹150-200 and ₹250-300). Each bar should be labeled at the base with the respective earnings range, and the height should correspond to the number of stores. This will give you a clear and correct histogram representation of the given data.
