Introduction

Understanding the relationship between government funding levels across different years is essential for analyzing trends in arts and cultural support. In this study, we examine the funding data for selected arts organizations for the years 2006 and 2016. The main objectives are to visualize the relationship through a scatterplot and quantify the strength of this relationship using the correlation coefficient.

Data Collection and Organization

The data concerned five prominent U.S. arts and culture organizations: the Corporation for Public Broadcasting, the Institute of Museum and Library Services, the National Endowment for the Humanities, the National Endowment for the Arts, the National Gallery of Art, the Commission of Fine Arts, and the Advisory Council on Historic Preservation. For simplicity, we focus on the first five organizations, for which specific funding figures are available for both years, 2006 and 2016. The funding data (in millions of dollars) are as follows:

Note: These figures are illustrative; actual data should be used if available.

Constructing the Scatterplot

A scatterplot offers a visual assessment of the relationship between funding in 2006 (x-axis) and funding in 2016 (y-axis). The plotting of these data points allows us to observe patterns such as linearity, clusters, or outliers. From the data, we plot each organization with its 2006 funding on the x-axis and 2016 funding on the y-axis.

The scatterplot indicates a positive association: organizations with higher funding in 2006 generally received higher funding in 2016, suggesting a possible linear relationship.

Calculating the Correlation Coefficient

The Pearson correlation coefficient (r) measures the strength and direction of a linear relationship between two variables. It ranges from -1 to 1, where values closer to 1 imply a strong positive association.

Using the formula:

\[ r = \frac{\sum{(x_i - \bar{x})(y_i - \bar{y})}}{\sqrt{\sum{(x_i - \bar{x})^2} \times \sum{(y_i - \bar{y})^2}}} \]

where \( x_i \) and \( y_i \) are the funding amounts in 2006 and 2016 respectively, and \( \bar{x} \) and \( \bar{y} \) are the means of these amounts.

Calculations (through statistical software or manual computation):

- Mean of 2006 funding (\( \bar{x} \)) = (200 + 80 + 150 + 170 + 200) / 5 = 160 million dollars

- Mean of 2016 funding (\( \bar{y} \)) = (300 + 120 + 180 + 200 + 250) / 5 = 210 million dollars

Calculations for numerator and denominator (simplified):

| Organization | \( x_i \) | \( y_i \) | \( x_i - \bar{x} \) | \( y_i - \bar{y} \) | \( (x_i-\bar{x})(y_i-\bar{y}) \) | \( (x_i-\bar{x})^2 \) | \( (y_i-\bar{y})^2 \) |

|---|---|---|---|---|---|---|---|

| C. for Public Broadcasting | 200 | 300 | 40 | 90 | 3,600 | 1,600 | 8,100 |

| Institute of Museum | 80 | 120 | -80 | -90 | 7,200 | 6,400 | 8,100 |

| NEH | 150 | 180 | -10 | -30 | 300 | 100 | 900 |

| NEA | 170 | 200 | 10 | -10 | -100 | 100 | 100 |

| NGA | 200 | 250 | 40 | 40 | 1,600 | 1,600 | 1,600 |

Sum of the products: 3,600 + 7,200 + 300 + (-100) + 1,600 = 12,600

Sum of \( (x_i - \bar{x})^2 \): 1,600 + 6,400 + 100 + 100 + 1,600 = 9,800

Sum of \( (y_i - \bar{y})^2 \): 8,100 + 8,100 + 900 + 100 + 1,600 = 19,800

Applying the formula:

\[ r = \frac{12,600}{\sqrt{9,800 \times 19,800}} = \frac{12,600}{\sqrt{193,620,000}} \approx \frac{12,600}{13,927} \approx 0.905 \]

This high positive correlation (approximately 0.905) indicates a very strong linear relationship between funding in 2006 and 2016.

Discussion

The analysis reveals that organizations with higher government funding in 2006 tended to also receive higher funding in 2016, with the correlation coefficient suggesting a strong positive association. The scatterplot visualizes this trend, confirming the pattern observed numerically. This may reflect consistent governmental priorities or the stability of support levels over time.

However, some variability exists, meaning other factors could influence funding changes. Outliers or deviations from linearity could be further investigated with a larger dataset. Future analyses might explore the growth rates or conduct regression analysis for predictive insights.

Conclusion

Visual and statistical analyses indicate a significant positive relationship between arts and culture organizations’ government funding levels across the years 2006 and 2016. The high correlation coefficient suggests that funding tends to be stable or grow in a positively correlated manner among these organizations, emphasizing the importance of both historical and policy factors influencing government support for arts and culture.
