Case Study – Visa Inc.

Visa Inc. operates the world's largest retail electronic payments network and is one of the

most recognised global financial services brands. It facilitates global commerce through the

transfer of value and information among financial institutions, merchants, consumers,

businesses and government entities.

To address online fraud, Visa requires information on the effectiveness of its online security system

via customer experiences with fraudulent behaviours in order to maintain and/or improve Visa’s

market share.

The research team, which you are part of, has collected data to assess the effectiveness of Visa Inc.

online security system. Data on customer experience regarding personal fraud is also collected. A

simple random sample of 2000 customers was selected. Of the 2000 customers to whom surveys were

sent, 420 responded. The survey used to collect data is provided below and the survey responses have

been collated in the dataset named Visa_Inc.xlsx file available under the Assessment folder in UoN

Blackboard. You are required to write a report after performing analysis on the data collected from

the customers of Visa Inc.

A member of the research team has suggested that a series of hypothesis tests should be conducted

to examine the following:

1. Is the number of card fraud experience the same across gender?

2. Are there differences across the age groups regarding card fraud?

3. What is the average time lost in resolving a card fraud? If Visa Inc. has set a time-period

which is acceptable at 12 hours, will this be a significant improvement to the response time

compared to what customers have experienced before?

4. How often does an online or offline card fraud occur? Visa Inc. is willing to invest in an

updated online security which will decrease the number of online card fraud only if online

transactions are more vulnerable to fraud compared to offline transactions. What is your

recommendation?

5. Do any of the customers’ satisfaction scores of ‘response time’, ‘the level of advice’, and ‘the

level of communication’ influence the overall satisfaction with the credit card fraud

resolution team?

Required:

Write a data analysis report that provides the results to each of the five hypothesis tests above and

make overall recommendations to Visa Inc. that management can use for future business decision-

making. Based on your analysis relating to these hypotheses, your report should focus on two key

issues: the current experience of personal fraud and the strategy or strategies that would be most

effective to increase customer satisfaction.

Report Structure

Please follow the following sequence in the report structure:

? Executive Summary

? Introduction

? Research Design

? Hypothesis Development

? Statistical Technique and Justification

? Results, and Statistical and non-statistical interpretation

? Analysis and Summary of the statistical results

? Recommendations

? References

Executive Summary

This section should provide a brief overview of the data analysis report. You should discuss the subject

matter, the method of analysis, the findings and recommendations and any limitations of the report.

It is suggested that the Executive Summary should be the last section that you write.

Introduction

Provide a brief background to the case to put your analysis in context. Provide a discussion of the

objectives of your analysis.

Research Design

Discuss the data collection process and the sampling procedures that were applied. In this section,

you should also outline the ethical considerations that would have been taken into account when

collecting data from this survey and reporting your results. This section should include references.

Hypothesis Development

You need to develop hypothesis linked to each question on page 2. You should mention the question

first and then write corresponding null and alternate hypotheses.

For example:

Question: How much are potential patrons willing to pay for the entrées? Is the $18 amount from

the forecasting model the correct value to use when setting food prices?

Null hypothesis (H 0 ): The average amount patrons are willing to spend on the entrée course is equal

to $18.

Alternate hypothesis (H A ): The average amount patrons are willing to spend on the entrée course is

not equal to $18.

Statistical Technique and Justification

You should categorically mention which statistical technique is used to test a particular hypothesis.

Sufficient justification should be provided for choosing a statistical technique. You should mention

Page 6 of 7

whether you are comparing the means or measuring the degree of relationship between/among the

relevant variables. Use credible academic references.

For example:

To test hypothesis one, one-sample t-test is used as this is the appropriate test to compare the

difference between mean of one variable and a pre-determined mean (Zikmund, Babin, Carr, &

Griffin, 2012, p. 520).

Results, and Statistical and non-statistical Interpretation

In this section, you should present your empirical result and then provide statistical and non-statistical

interpretation of the result.

For example:

Table 1: One-sample t-test for difference in patron expenditure

Variable 1 Variable 2

Mean 20.14118 18

Variance 91.85022 0

Observations 340 340

Hypothesized Mean

Difference 0

df 339

t Stat 4.119569

P(T<=t) one-tail 2.39E-05

t Critical one-tail 1.649361

P(T<=t) two-tail 0.0000477

t Critical two-tail 1.966986

Statistical interpretation:

From Table 1, it is evident that t-calculated (4.119) is greater than t-critical (1.967) and p-value is less

than the significance level (5% level of significance), thus, we can reject that null hypothesis that the

average patron is willing to pay $18 for their entrée (p-value 0.0000477) at 5% level of significance.

Non-statistical interpretation:

The average expenditure ($20.14) is greater than $18 (value obtained from forecasting model).

Therefore, the average expenditure value should be used when pricing foods in the restaurant.

Analysis and Summary of the Statistical Results

Synthesise the hypothesis test results as they relate to the two key research questions: the current

degree of customer satisfaction and the strategy or strategies that would be most effective to

Page 7 of 7

increase customer satisfaction. Report a summary of your key findings and the conclusions that can

be derived from this analysis.

Recommendations

Provide recommendations to Visa Inc. Each recommendation should be linked to one of your key

findings presented in the previous section. Bullet points can be used for the recommendations.
