Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
he Swamp Palace Museum (SPM) is an interactive museum that teaches visitors the ways of life on the swamps of the southern United States. Visitors can visit over 100 exhibits demonstrating the ecology of the swamp and the habits of the animals and insects that call the swamp home. Additionally, the museum includes several fast-food and full service restaurants and opportunity for swimming and several thrill rides.
The park was originally supported with one time government funding but now it has to become self-supporting. After five years of operation, the park has not lacked for visitors but has struggled just to break-even. The Swamp Palace has sought help from the Marketivity Group to help them address the long-term viability of the park.
Several technologies are considered as ways of enhancing value. One is a mobile phone app that will provide oral and visual navigation aids around the park. For instance, if someone says “take me to the Blind Bayou Bar,” the phone will give directions using prominent museum landmarks. Second, Swamp Palace is considering subscribing to an Internet coupon program that would provide patrons with discounts.
Marketivity implements a quasi-experimental design over a one-week period in August. A sample of 200 visitors is randomly intercepted before entering the park. Approximately half are given the opportunity to download a free navigation app for their cell phone. Similarly, about half are invited to go to a kiosk and download a coupon from the Internet. Upon exiting the park, the patrons are taken to a desk where they fill out a short questionnaire. The employee then keys the data into the computer. The variables are in the dataset that is posted on BB.
