Solution
The histogram in the image appears to represent monthly rainfall data ("Curah Hujan Bulanan") in millimeters. Based on its shape, we can attempt to determine the distribution it resembles:
-
Right Skewness: The histogram has a longer tail to the right, suggesting it may be skewed right. This is typical of rainfall data, which often follows a positively skewed distribution.
-
Possible Distribution:
- Exponential Distribution: This is possible for rainfall, where many months have low rainfall and fewer months have extreme rainfall.
- Gamma Distribution: Often used for rainfall, as it can model skewed data with a non-negative range.
- Log-Normal Distribution: If the log-transformed data produces a symmetric distribution, it may follow a log-normal distribution.
- Normal Distribution: While it is somewhat symmetric in the middle range, the skewness makes it unlikely to follow a true normal distribution.
To confirm the exact distribution, statistical fitting or goodness-of-fit tests (e.g., Kolmogorov-Smirnov test) would need to be performed.
Would you like me to:
- Fit the data to a specific distribution?
- Explain any of these distributions in more detail?
- Guide you on how to calculate goodness-of-fit tests?
- Provide Python code for further analysis?
- Explore how to transform the data for symmetry (e.g., log transformation)?
Tip: Always visually inspect the histogram and combine it with statistical tests to confirm the distribution type
