Ishu was given an individual task of collecting weather reports for a week. Identify where Ishu went wrong from the assessment indicators given below :

The correct answer is Option 3: She concludes that decreased humidity increases the likelihood of rainfall.

Step-by-Step Explanation:

1. Understanding Humidity and Rainfall:
Humidity is the measure of the amount of water vapor present in the air. For rainfall to occur, air must contain high moisture levels (high humidity) so that water vapor can condense into clouds and precipitate as rain.

2. Analyzing the Error:
A conclusion stating that decreased humidity increases the likelihood of rainfall is scientifically incorrect. In reality, high humidity—not low/decreased humidity—increases the chances of rainfall.

3. Evaluating Other Indicators:
- Tabulating weather data daily is a good scientific practice.
- Predicting that rain may or may not occur is a standard probabilistic interpretation of weather forecasts.
- Recognizing daily variations in maximum and minimum temperature shows correct observation of weather patterns.

Therefore, Ishu went wrong in concluding that decreased humidity increases the likelihood of rainfall.
