Construct a model using a dataset of popular songs to predict rating based on auditory features of the songs included in scoringData.csv.
PREDICTIVE ANALYSIS COMPETITION(PAC) What makes some songs become popular? Construct a model using a dataset of popular songs to predict rating based on auditory features of the songs included in scoringData.csv. Submissions will be evaluated based on RMSE (root mean squared error)(Wikipedia). Lower the RMSE, better the model.
Create a simple distribution graph (histogram) where we will explore the age of women after giving birth to their first child.
Using the Gestation Demographics SEU dataset This week we are learning about ordinal/categorical, continuous, and dichotomous variables. Using the Gestation Demographics SEU dataset that is located in the tabs at the bottom of the Framingham dataset provided, perform the following problems using R Studio or Excel. Create a simple distribution graph (histogram) where we will […]

Is the average failed campaign goal from 2016 significantly different from a goal of $10,000? Support your answer with your p-value and the mean of the failed campaign goals.
ASSIGNMENT QUESTION 1: Use the mean() function to find out the mean of the successful sample. Why do you think the Wired campaign suggested a mean of $10,000? Answer: QUESTION 2: Is the average failed campaign goal from 2016 significantly different from a goal of $10,000? Support your answer with your p-value and the mean […]
Use the Excel Dataset from Exercise 1 to (a) run a Pearson’s r to determine if there is a correlation between BMI(before) and Resting Pulse Rate; and (b) a Spearman’s rho to determine if there is a relationship between BMI(groups) and Hypertension(groups). Perform both tests in Excel. Write up your results for both tests in an APA paper.
