Welsh 9th Grade

The statistical analysis conducted on geographies consisting of 528,596,253 people shows a mild positive correlation between the proportion of Welsh and percentage of population with at least 9th grade education in the United States with a correlation coefficient (R) of 0.399 and weighted average of 96.4%. On average, for every 1% (one percent) increase in Welsh within a typical geography, there is an increase of 0.039% in percentage of population with at least 9th grade education.

It is essential to understand that the correlation between the percentage of Welsh and percentage of population with at least 9th grade education does not imply a direct cause-and-effect relationship. It remains uncertain whether the presence of Welsh influences an upward or downward trend in the level of percentage of population with at least 9th grade education within an area, or if Welsh simply ended up residing in those areas with higher or lower levels of percentage of population with at least 9th grade education due to other factors.
