Assignment #1: Statistics Data Analysis Plan

Assignment #1: Prepare Descriptive Statistics Data Analysis Plan

Before conducting any statistical analyses, researchers develop a plan for how they will analyze their data to answer their research questions. The purpose of this assignment is to provide experience developing and executing a descriptive statistics analysis plan using real world data to answer a practical question.

Note: This first assignment develops and executes a preliminary plan using a subset of the data to create tables and graphs to address the assigned task. The second assignment will involve carrying out the plan in greater detail, after receiving in class feedback from your instructor. 

Assignment Steps:
