The link between metric systems, scientific literacy and attitude.
We previously reported our findings using 200 participants. The survey received 300 responses recently, and enabled us to analyze the link of proficiency of metric systems to scientific literacy and attitude toward science.
First, we found the scientific literacy is significantly associated with proficiency of metric system (Figure 1), which is perhaps not a surprise because science is taught in the metric system. This correlation suggests that people that are familiar with scientific knowledge are also more proficient at metric usage.
Second, we found that attitude toward science is significantly associated with proficiency of metric usage (Figure 2). Attitude toward science is also directly associated with scientific literacy (data not sure),
Third, we found that attitude toward science is significantly associated with age, suggesting that old people tend to have better attitude toward science, even when metric proficiency is controlled (Figure 3).

We need a large data and more broad sampling scale to make this survey more meaningful. Please help us persuade more people to take this on-line survey.

Note on 2013 Nov 15, I may use interaction and auto-correlation to address the sampling bias.
