Research Question Part 1: Pearson r correlations We will explore the question about the type of person who likes online dating by asking: Is dating online related to how much the person wants to be in a relationship? Also, is dating online related with how extroverted the person is? To receive credit for this assignment, answer what is highlighted. When completed, upload the file to the Variables: Variable Measurement scale Scores Online dating attitude How do you feel about dating 1 I don't favor it online? 5=I very much favor it Relationship desire How much do you 1=Not so much Extroversion want to be in a relationship? How extroverted do you feel you are? 5=Very much so 1=Not at all 5-Very much so 1. Look at the table below to answer questions about the relationship between online dating attitude (x) and relationship desire (y): What is the correlation coefficient? How strong or weak is the relationship? What is the direction of this relationship? State your decision (Step 4) and conclusion (Step 5): How favorable or Pearson Correlations unfavorable do you feel Correlation towards online dating? Sig.

What is the correlation coefficient? How strong or weak is the relationship? What is the direction of this relationship? State your decision (Step 4) and conclusion (Step 5)? 4. Now compute by hand, based on the relationship between online dating attitude & extroversion: The proportion of the variance accounted for (r). The proportion of the variance not accounted for (1-r) 5. Based on the same relationship above, look at the table below in order to state the linear regression equation for predicting dating attitude from extroversion. First, find b (slope) and a (intercept), and then: State the linear regression equation: Model 1 (Constant) How social or extroverted are you?

Dependent Variable: How favorable or unfavorable do you feel towards online dating? Now go on to Part 2 Part 2: Chi Square test of independence We will explore the question about whether political party is independent of gender. The first table (Sex* Party Affiliation Crosstabulation), displays the observed and expected frequencies. The second table (Chi Square Tests) shows information you will need to answer the questions below: How many participants were there in this study? What is the Chi square coefficient (chi square obtained)? Based on the Chi Square Test table, state the decision (STEP 4): State the conclusion (STEP 5): Sex Party Affiliation Crosstabulation Party Affiliation republican democrat other Total Sex female Count 18 43 14 75 Expected Count 27.6 31.9 15.5 75.0 male Count 39 23 18 80 Expected Count 29.4 34.1 16.5 80.0 Total Count 57 66 32 155 Expected Count 57.0 66.0 32.0 155.0 Chi-Square Tests Asymptotic Significance Value df (2-sided) Pearson Chi-Square 14.151 2 .001 Likelihood Ratio 14.419 2 .001 Linear-by-Linear 3.070 1 .080 Association N of Valid Cases 155 a. O cells (0.0%) have expected count less than 5. The minimum expected count is 15.48. Part 3: Frequency Distribution 1.
