Assigned news outlet: The BBC Part 1 Part 1a. Continuous Independent Variable (Qualtrics Data) Step 2: Numeric summary of the average score Mean Median Mode Standard Dev Range Variance Competence 5.13 5 6 0.934 4.33 0.871 Step 2b: Written summary of calculation procedure First, our group calculated the mean/average response recorded per each individual's answer across our questions measuring the final independent continuous variable, perceived competence. The topics evaluated by respondents were, "The BBC covers a variety of topics/events," "The BBC is accurate in its reporting," and "The BBC tells well-rounded stories." We measured the mean number from a scale of 1-7 between each of the questions for the rows, AE, AF, and AG. Once we calculated the mean answers on the scale of the variable, perceived competence, we calculated the mean, median, mode, standard deviation, range, and variance based on these mean scores in row AH2:AH:40. For the mean, we used the equation, =AVERAGE(AH2:AH40). For the median, we used the equation =MEDIAN(AH2:AH40). For the mode of the data, we used the equation, =MODE(AH2:AH40). For standard deviation, we used the google sheets formula, =STDEV(AH2:AH40). For the range, we used the formula, =MAX(AH2:AH40)-MIN(AH2:AH40), and for the variance, we used the equation, =VAR(AH2:AH40). Step 3: Written summary for Independent Variable On average people felt that the BBC is mostly competent (mean =5.13), with a standard deviation of 0.934. Scores ranged from 2.667 (mostly not competent) to 7.00 (very competent). Part 1b. Readership Dependent Variable (AverPoint Data) Step 4: Numeric summary of the Dependent Readership Variable Mean Median Mode Standard Dev Range Variance Minutes Read 0.349 0 0 0.828 3 0.685 Articles Read 0.628 0 0 1.047 4 1.10 Step 5: Written summary of the Dependent Readership Variable On average, people did not spend too much time reading BBC articles (mean = 0.349), with a standard deviation of 0.828. Scores ranged from 0 minutes read to 3 minutes read. On average, people did not read many BBC articles (mean = 0.628), with a standard deviation of 1.047. Scores ranged from 0 articles read to 4 articles read.

Part 2 Part 2a. Relationship between a continuous IV and readership DV Step 2: Tableau Scatterplot Step 3: Written summary of the relationship between the continuous IV and DV. Individuals who perceived the BCC to be more competent were more likely to read BCC news. (Pearson’s correlation value: 0.076). Part 2b. Relationship between a categorical IV and readership DV Step 1: Categorical variables: PIVOT table (average of the DV per category)
