Correlation and regression analysis allows us to determine the strength of a linear relationship, the direction of a linear movement, and if a relationship exists between two variables (Donnelly, 2013). In this scenario, a student intern noticed a possible correlation between the customer’s satisfaction and the total amount of the bill. The intern decided to collect 100 customer satisfaction surveys and match each of them with the corresponding total bill. The intern wants to use the collected data to develop a hypothesis, conduct a test for correlation, and develop a prediction equation for customer satisfaction. I will assist the student intern by developing an appropriate hypothesis for the data collected, conducting a test for correlation, developing a prediction equation for customer satisfaction, and analyzing the results to better inform the owners. Correlation and regression analysis will tell us if a relationship exists between customer satisfaction and the total amount of the bill and it will tell us the strength of the relationship. Currently we are unsure if there is a relationship between the two variables, so we need to develop a hypothesis and determine the correlation coefficient. Since we are only looking to see if there is a relationship between the two variables, we will create a hypothesis that answers this question. The null hypothesis will be that the population correlation coefficient equals 0 and the alternative hypothesis will be that the
Observed customer satisfaction survey consequence displays poor decisions made by Samsung. Sequence, base on the observation data there were positive and negative aspects of the research of observational data. The experiment was complete covering all elements of this population, moreover, included the smallest statistical measurable details of the quality and value of the product, number of return
The Purpose: Today’s society focuses on customers’ satisfaction, most business ask the consumer to take surveys to learn more about their experience. It is highly important to make sure our customers leave happy and satisfied with our service, and if they feel any different we need to get
The Barbie Bungee lab was conducted in order to find the association between the amount of rubber bands and the distance the Barbie bungeed. Before performing the final experiment, the group conducted an initial investigation to get data that could be analyzed to examine the comparison from the amount of rubber bands to the length Barbie was able to bungee. In the investigation rubber bands would gradually be added one by one starting at two rubber bands. Each time a rubber band was added, three trial bungees were done and the lengths the barbie dropped were recorded. Using data collected from our background investigation, the group used excel to create a sheet displaying the data in a table, a graph showing the correlation constant, the line of best fit. The line of best fit was in slope-intercept form (y=mx+b) where y represents the length of the trial average; m represents the slope
Customer satisfaction can be gauged by a number of indicators including fewer customer complaints, less product returns, a greater number of customer referrals, and a greater number of referrals per customer. An increase in customer requests for new products or services would demonstrate greater customer interest. Customer satisfaction and brand name awareness can also be gauged through either in-store or internet based surveys.
In this essay I will describe correlation is a measure of association as well as describe different methods of establishing a correlation between variables. In this essay I will also explain advantages and disadvantages of each method, were each must be applied, and provide particular circumstances and examples in which a researcher may want to establish correlation
The analysis of variance of regression showing the overall customer satisfaction and its relation with the price gives the following outcome.
A correlation research determines whether or not at least two variables are correlated. An example scenario, when it would be advantageous for researchers to use correlation research design, is to examine if there is any correlation exists between family income and SAT scores. The researcher describes the relationship between these two variables by checking whether an increase or decrease in family income corresponds to an increase or decrease in the SAT scores. A positive correlation exists between family income and SAT scores when family income increases lead to an increase in the SAT scores and a decrease in family income leads to a decrease in the SAT scores. A negative correlation exists when an increase in family income leads to a decrease
As you can see, a 5% increase in the percentage of active members within their existing members (retention/loyalty) would result in a 9.4% increase in revenues. If HHonors had a 5% increase in active members and each active member stayed only 1 additional night during the year HHonors would see a 31.7% increase in revenues. The best part is that we know from research and history that initial customer acquisition is the most expensive part
Come up with an example of a hypothesized correlation between the quantity of a product consumed and a specific background variable of consumers.
(10 points) As a CEO you wish to maximize the productivity of your workers. You are thinking about providing your employees with smartphones so they can be readily available to clients and increase sales. However, you are also concerned that your employees are just as likely to download apps that will distract them from their work, leading them to play games and update their social networking sites rather than focus on the job of pleasing clients. To test this you randomly select 6 employees for an experiment. You provide 3 with the new smart phone and the other 3 use their existing technology. The following chart shows their changes in sales. Based on this small sample, what is the correlation between smartphone and increase in sales? [Hint: It may help to use the spreadsheet function CORREL to calculate the correlation. Also, enter the correlation in percentage terms with no more than two decimals, but do not enter the % sign. ] {Anthony, Smartphone: Yes; change in sales 60; Kira,
The method of the study was an ex post facto correlational study and somewhat vague. The hypothesis was clearly stated in this article and two were used. The two used were, “No correlation exists between the hospitals allied health care department’s revenue and various measures of allied health care customer satisfaction from April 2008 to April 2010” and “A correlation exists between the hospital’s allied health care department’s revenue and various measures of allied health care customer satisfaction from April 2008 to April 2010” (Ellis-Jacobs, 2011, p. 2). The article also discussed the research question for the study which is, “what is the relationship, if any, between allied health care practitioners’ customer service skills and a hospital’s gross revenue” (Ellis-Jacobs, 2011, p. 2).
To distinguish if any major changes had occurred in students behaviors the researchers performed a regression analysis, meaning, that if there was a strong tie in the data between any two variables if would show a high correlation coefficient. A coefficient near 0 indicates no relationship, a coefficient of 1 or more shows a considerable change.
That is, we need to provide the client with a list of priority items that can be improved and that will have a positive impact on overall satisfaction or customer loyalty and retention. Typically, the goal is to establish the list of priorities and relative importance of the explanatory variables, rather than try to predict the mean value of customer satisfaction if these improvements were implemented. Since most CSAT studies are tracking studies, the results can be monitored over time to determine if the desired changes are occurring. We must be sure that changes in the results are in fact customer response to the client’s marketing efforts and not just phantoms of the analytic tool used to build the model. The latter often happens as a result of multicollinearity, which is a serious problem in many CSAT studies and presents two challenges in modeling CSAT data. The first is accurately reflecting the impact of several independent variables that are highly correlated. The second is insuring that the results are consistent wave to wave when tracking a market over time. This paper illustrates the problems that multicollinearity present in modeling data and then compares the results from the four aforementioned modeling techniques.
Research is conducted beforehand in order to identify the characteristics that are crucial to customer satisfaction.
The subject company is an IT Call Center, which is in a highly competitive industry due to it being the fastest growing industry in the world. With competition being so fierce, this creates low prices in the given market. Subsequently, for an organization to maintain market share and profitability, it must offer the best service in the market. The call center provides services to a variety of customers such as online and telephone services. The responsibilities of a call center are to handle questions from clients with problems. The company purchased industry data from a clearinghouse, which gathers a variety of information about customer satisfaction and call center technical and business performance. By comparing their company to the industry standards, they discovered their customer satisfaction was average or below the industry standard. The company’s satisfaction rating is 73% on a 100% standardized score, whereas the industry average is 76% and best in
