Part 1: Sampling Design

Scenario

Pear is a leading market shareholder in the cellular phone markets holding a market share of 43.1 percent making them the market leader (comScore.com, 2015). Though they are at the top they are concerned about their competitors such as Hamsong, LB, Kotorala, and HVC stealing their customers. Pear has decided to put a team together in order to identify one dependent variable and one independent variable, conduct surveys of their current customers to understand the total number of abandonments the company has had in a three month period and obtain a measure of how many times a Pear customer calls customer support or visits the “brain bar” at the Pear store. In the same period the team will measure the number of customers who move from the iPear to one of their competitors.The research team will use the chosen variables to develop questions and a hypothesis based on these questions.

Variables

The independent variable of focus is number of abandonments, defined as customers who leave Pear for a competitor. The dependent variable of focus is how often a customer calls customer support or visits the “brain bar” at the Pear store.
