When the Senate held a vote for the legislation: Democrats supported it 46 to 21 and Republicans supported it 27 to 6. The Purpose of this analysis is to determine whether or not there is a significant association between the two parties and the support of the Civil Rights Act of 1964.
In Congress (which consists of the House of Representatives and the Senate) there were 520 congressmen who voted for or against the Civil Rights Act of 1964. Out of those Congressmen
who voted there were 198 Democrats and 165 Republicans who supported the legislation, making a total of 363 congressmen who were for the Civil Rights Act of 1964. These statistics show that there was support on both party sides for this piece of legislation. However, out of the Congressmen who voted there were 117 Democrats and 40 Republicans who opposed the legislation, make a total of 157 Congressmen who were against the Civil Rights Act of 1964. These statistics show that there was also opposition for this piece of legislations from both parties. Looking at just the Democrats in congress who voted 62.86% of those voted for this legislation and 37.14% of those voted against this piece of legislation. Looking at the opposite party, the Republicans had 80.49% of their congressmen support this legislation and only 19.51% oppose it. Based on all of these statistics, out of both of the parties, the Republicans look to have a greater support for the Civil Rights Act of 1964. When looking at the percentages of each party on voting for the Republicans look to have a great amount of support in their party (which was 80.49% support), compared to the Democratic Party which only had 62.86% of their party supporting the Civil Rights Act of 1964.
For this analysis of the Civil Rights Act of 1964, the Research Question is: Is there a significant association between the two parties and support of the Civil Rights Act of 1964?
The Null Hypothesis being tested is: there is no significant association between the two parties and the support of the civil rights act of 1964. The Research Hypothesis is: There is a significant association between the two parties and support of the Civil Rights Act of 1964 such that: If you are a part of the Republican party you are more likely to support the Civil Rights act of
1964.
In order to determine if there is or is not a significant association between the two parties and support of the Civil Rights act of 1964, a Chi Square test needs to be completed.
When conducting the test one would use 2 types of categorical information: Political Party and Support for the Civil Rights Act of 1964. Next creating the Chi Square, and then determining the expected numeral for the data. Comparing the difference between the observed data versus the expected data, one can then calculate the Chi Square Statistic. When calculating these data points for this analysis, we find that the chi square statistic is 18.3143. Next, we determine the critical limit at alpha 0.05, which is 3.841. The last step into completing the Chi Square Analysis is to draw a graph to help interpret the data we have found. We will use the critical limit in order to determine the Beta and the Alpha regions within the graph. We next can take the Chi Square Statistic and plot it on the graph to visualize which region the data falls within. For this instance the Chi Square Statistic falls with in the Alpha region, meaning we can reject the Null Hypothesis, and there is a significant
difference.
The Null Hypothesis that is being tested is: there is no significant association between the two parties and the support of the civil rights act of 1964. This Null Hypothesis can be rejected at alpha 0.05 because there is a significant association between the two parties and the support of the Civil Rights Act of 1964, such that; the republican party is largely associated with being in favor for the Civil Rights Act of 1964. When looking at the Congressmen who were associated with this piece of legislation, it can be concluded that Republicans were more likely to side with Civil Rights Acts during this time period, which can be confusing to people who did not grow up during this time period. Before the present day political parties, Republicans were more likely to be a part of the civil rights acts and Democrats were those who opposed them. The parties were basically switched from what they are today. Up until about the late 1980s and early 1990s the Democrats were those who were against civil rights and in the present day Republicans are less likely to support civil right legislations or movements.
