THE IMPACT OF INDEPENDENT VARIABLE ON DEPENDENT VARIABLE
THE IMPACT OF [INDEPENDENT VARIABLE] ON [DEPENDENT VARIABLE] CONTROLLING FOR [CONTROL VARIABLE] [Your Name] PLS 401, Senior Seminar Department of Public & International Affairs UNC Wilmington 1/24/2022 1
Univariate Hypothesis • Theory: –X –X • H 1: predict the distribution of values across the categories of your dependent variable. If relevant, predict whether you expect to find a conflict or consensus distribution. 1/24/2022 2
Table 1 [insert the SETUPS frequency table for your dependent variable] 1/24/2022 3
Univariate Findings • H 1 ([restate hypothesis]) is [supported/ not supported / contradicted] by the sample data in Table 1 because: 1. The pattern predicted by H 1 [is/is not observed in/is contradicted by] the sample data. 2. The pattern observed in the sample [is/is not] statistically significant. The random-sampling error margin for this size sample is [± x %]. 1/24/2022 4
Bivariate Hypothesis • Theory: –X –X • H 2: [one category of the independent variable] is more likely than [another category of the independent variable] to [exhibit a particular value of the dependent variable]. [for example: males are more likely than females to support the death penalty – where gender is the independent variable and attitude toward the death penalty is the dependent variable] 1/24/2022 5
Table 2: [insert the bivariate SETUPS table and include the tau-b & chi-squared probability statistics] 1/24/2022 6
Bivariate Findings • H 2 ([restate the bivariate hypothesis]) is [supported/ not supported/is contradicted] by the sample data in Table 2 because: 1. The pattern predicted by H 2 [is/is not] observed in the sample data. The tau-b is [x. xx] which indicates that the relationship is [weak/moderate/strong]. 2. This sample finding [is/is not] statistically significant. The chi-squared probability of random-sampling error [is/is not] less than 0. 05 (it is [x. xx]). 1/24/2022 7
Multivariate Hypothesis • Theory: – X • H 3: controlling for [the control variable] [does / does not] change the impact of [the independent variable] on [the dependent variable] across the partial tables. – In the [first partial-table subgroup], the bivariate relationship will be [weaker / the same / stronger] than in the total population. – In the [second partial-table subgroup], the bivariate relationship will be [weaker / the same / stronger] than in the total population. – Add a prediction for the 3 rd partial-table subgroup, if necessary. 1/24/2022 8
Table 3 a [insert the first SETUPS partial table and include the tau-b & chi-squared probability statistics] 1/24/2022 9
Table 3 b [insert the second SETUPS partial table and include the tau-b & chi-squared probability statistics] 1/24/2022 10
Table 3 c [if necessary, otherwise delete this slide] [if necessary, insert the third SETUPS partial table and include the tau-b & chi-squared probability statistics] 1/24/2022 11
Multivariate Findings • H 3 ([restate the multivariate hypothesis)] is [supported / not supported / contradicted] by the sample data. 1. The strength of the bivariate relationship [did / did not] change as predicted in the partial-table subgroups. [Report and interpret the tau-b statistics] 2. The statistical significance of the bivariate relationship [did / did not] change in the partial-table subgroups. [Report and interpret the chi-squared probability statistics] 1/24/2022 12
