T-test: Comparing VOC Efficiency Between Leaf Size

This page shows the result of a two-sample independent t-test that compares VOC Efficiency (μg/cm²) between plants with Small vs. Large leaves.

Purpose of the Test:
The t-test was used to determine if the difference in VOC efficiency between the two groups is statistically significant or simply due to random variation.

How It Worked:

• The VOC efficiency data were split into two groups based on leaf size.

• A two-tailed t-test was run using scipy.stats.ttest_ind() assuming unequal variances.

• The resulting t-statistic was 1.357, and the p-value was 0.189.

What It Means:
Since the p-value is greater than 0.05, we fail to reject the null hypothesis, meaning:

There is no statistically significant difference in VOC efficiency between small-leaf and large-leaf plants in this dataset.

This statistical result supports the visual patterns seen in your boxplot and violin plot, but confirms that the variation may not be conclusive from a statistical standpoint.
