2.1: Ordinal variable
For your ordinal variable:a) provide an ordered table containing the frequency, relative frequency, cumulative frequency, and totals, b) generate a pie chart and an ordered bar chart, and c) discuss the distribution of the variable and whether the order of the categories reveals something about the trend.
Section 3: Multivariate descriptive statistics and visualizations
You may want to review group projects to ensure you complete the expected thorough presentation of each task.
3.1: Bivariate Analysis of Two Qualitative Variables
Provide the following: a) a contingency table containing the frequency, relative frequency, row percent, and column percent of the groups b) a side by side bar chart, c) a 100% stacked bar chart of row percent, d) a response to the statistical question that uses evidence from the analysis as support.
3.2: Bivariate Analysis of a Quantitative Variable and a Qualitative Variable
Provide the following: a) a table containing the descriptive statistics for each group, b) a side by side box-whiskers plot, c) the 95% confidence interval for the mean of each group and the interpretation of each CI in context, and e)a response to the statistical question that uses evidence from the analysis as support.
3.3: Bivariate Analysis of Two Continuous Variables
Provide: a) a seed and draw an SRS where the sample size is equal to 10% of your data rows (round up if you get a decimal), b)a scatter plot of the sample with least squares regression line overlaid, c) a contextual interpretation of the correlation and of the slope, d) one prediction for the response variable using a value of the explanatory variable of your choosing and interpret the prediction in the context of the relationship, and e)a response to the statistical question that uses evidence from the analysis as support.
