Memo to: Nick at Zen Motors From: Carolyn Negron February 08, 2019 Nick! I hope you are doing well! I just wanted to touch base with you and go over a few of my findings. To further investigate our future market of car buyers and understand their beliefs towards the environment we need to select a sample to gather this information. Nick, I believe that stratified sampling will help us further understand the demographics. Because our research requires answers to specific types of questions, I would definitely chose this option to better understand the population. Additionally, stratified sampling is better to use since people who drive automobiles can fall in different categories. Categories specifically consisting of age, location, income and more. Stratified sampling separates the populations into different sub groups that are better known to researchers as strata. This helps marketers better understand each group and what they are looking for in a vehicle and how they feel about the environment. We should use disproportionate sampling size. In order to be efficient, I feel that this is the best size because it pulls from the different strata that I mentioned before. Confidence levels are by determined by how confident we feel that the results will repeat themselves. I think to better understand our data we should use a 95% because it will show us information under the normal bell curve. Thanks so much for taking a moment to hear my considerations for this project. Have a nice day! -Carolyn Negron
