About the Author s. Previous editions. Basic Business Statistics, 12th Edition. Relevant Courses. Sign In We're sorry! Rather than dwell on underlying formulas, we show how to use statistics to answer questions. Each case study begins with a business question and concludes with an answer to that question. Formulas appear only as needed to address the questions, and we focus on the insights into the problem provided by the mathematics.

The mathematics serves a purpose. The material in this casebook is organized into 11 "classes" of related case studies that develop a single, key idea of statistics. The analysis of data using statistics is seldom very straightforward, and each analysis has many nuances. Part of the appeal of statistics is this richness, this blending of substantive theories and mathematics. For newcomers, however, this blend is too rich, and they are easily overwhelmed and unable to sort out the important ideas from nuances.

Although later cases in these notes suggest this complexity, we do not begin that way. Core statistical concepts and skills have been augmented with practical business examples, scenarios, and exercises. H1: There is an association between Age of car buyer and Car Size bought. Therefore conclude that there is a statistical association between the age of a car buyer and the size of car bought.

Under 30's tend to prefer larger cars; year age car buyers marginally tend towards medium to large cars, while over 45's strongly tend to prefer smaller cars. Recommendation Target larger cars to the younger market and smaller cars to the older market. Therefore conclude that the proportion of people who read Sports News is the same in each Geographical Region. The evidence is however not strongly convincing. Therefore conclude that gender and preferred gym activity are associated.

New conclusion There is no statistical association between gender and gym activity i. Management conclusion By an inspection of the row percentage table in a , it can be concluded that spinning and swimming are the most preferred gym activities of females, while doing the circuit is the least preferred gym activity of females.

H1: The frequency of store visits per week differs significantly from the manager's belief. Therefore conclude that the shopping frequency of customers differs significantly from the manager's belief.

These differences are however not strongly significantly different. H1: There is a significant change in the equity portfolio mix between and Therefore conclude that there is no significant change in the equity portfolio mix of the investor between and The equity portfolio profile is essentially the same in as it was in H1: There is a significant change in the payment method for electronic goods.

Therefore conclude that there is a significant shift in payment practices from the past. H1: Limpopo sales pattern does not follow the national sales pattern. Therefore conclude that the Limpopo sales pattern of cereal package sizes differs significantly from the national sales pattern of package sizes sold.

By an inspection of the Limpopo sales profile relative to the national pattern, Limpopo tends to sell more large sized packages relative to the national pattern. The evidence is however not overwhelming i. Therefore conclude that the support for the present compensation plan is different in at least one of the provinces. H0: There is no association between payment plan preference and province.

H1: There is an association between payment plan preference and province. New conclusion There is no statistical association between payment plan preference and province. The sample evidence is not strong enough i. Technical defects however tend to be more prevalent during the night shift. Thus there does appear to be an association between shift and nature of tyre defects. H1: There is an association between nature of tyre defect and shift.

Therefore conclude that the nature of tyre defects produced is related to the shift on which the defects occur. The sample proportions being compared are: Morning Afternoon Night 0. Based on the row percentages table in a above, it is clear that the morning shift produces a proportionally larger percentage of defective tyres due to mechanical factors than the afternoon or night shifts.

Males, alternatively, are marginally more interested in the Sport and Business sections. These observational conclusions are, however, not overwhelmingly conclusive. H0: There is no association between gender and the newspaper section most preferred. H1 : There is an association between gender and the newspaper section most preferred. Therefore conclude that gender and the newspaper section most preferred are statistically associated.

The sample proportions being compared are: Sport Social Business 0. Based on the row percentages table in a above, it is clear that females tend to read the Social section most, with the Sports section read the least. H0: There is no change in the size of car loan applications from four years ago.

H1: There is a significant shift in the size of car loan applications from four years ago. Therefore conclude that there has been a significant shift in the size of car loan applications from 4 years ago. The shift has been towards larger car loan applications. H0: There is no association between milk type purchased and health-concious status. H1: There is an association between milk type purchased and health-concious status.

Therefore conclude that there is a significant statistical association between the health-concious status of a consumer and their preference for certain type of dairy milk products. The sample proportions being compared are: fat-free low-fat full cream 0. Based on the row percentages table in a above, it is clear that health-concious consumers tend to purchase more fat-free dairy products than full cream products. It is a measure of the level of influence of the treatment factor on the response measure.

Any differences can be attributed to or explained by the influence of the treatment factor on the numeric response measure. Conclusion: All population means are equal. Therefore conclude that there is at least one motor vehicle type with a different average fuel consumption to the rest. By inspection, it would appear that VW has an average fuel consumption that is significantly different higher, and hence least fuel efficient from Peugot and Ford.

Note: The sample evidence must be more convincing i. Assumption 2 A normally distribution population for the response variable. Therefore conclude that there is no difference in the mean volume of sales across the 3 package designs. All are likely to generate the same average sales. Therefore the cereal producer can choose any of the three package designs for their new muesli cereal. Therefore conclude that there is at least one bank that has a different mean service rating score to the other banks.

By inspection, it would appear that Bank X has a significantly higher mean service rating score than the other two banks. The three banks are perceived similarly by customers in terms of their service levels. Note: The reason for the change in conclusion between a and b is that the statistical evidence is only weak i.

Therefore conclude that there is at least one shelf height that generates a different mean level of sales to the other shelves.

By inspection, it would appear that shoulder and waist high shelves generate higher average sales of the drinking chocolate product than bottom or top shelves. Therefore conclude that there is at least machine that has a different mean processing time. By inspection, machine C has a significantly longer mean processing time than either machines A and B.

Machine C must not be considered for purchase. The population mean processing times between the two machines A and B are likely to be identical.

Thus the company can purchase either machine A or machine B. Therefore conclude that there is at least one sector with a different mean earnings yield relative to the other sectors. Therefore conclude that there is at least one advertising strategy that results in a different mean level of deodorant sales relative to the other strategies. On average, the Sophisticated and Trendy strategies appear to be equally effective the difference in sample means does not appear significant.

Recommendation: Either the Trendy or the Sophisticated strategy can be adopted. Therefore the population mean sales from each of the two strategies is likely to be identical. The two strategies are therefore equally effective and either can be adopted by the company. It appears the least effective. The remaining two strategies Sophisticated and Trendy are equally effective and therefore either can be adopted by the company to promote its new ladies deodorant.

These differences do appear to be significant. Therefore conclude that there is at least one sector with a different mean leverage ratio relative to the other sectors.

By inspection, the banking sector has the lowest mean leverage ratio, while construction and manufacturing appear to have similarly high mean leverage ratios.

Recommendation The investor is advised to consider either the banking sector with the lowest mean leverage ratio or the technology sector with a marginally higher mean leverage ratio. This difference may not be statistically significant. The population mean leverage ratios between the Technology and the the Banking sector are therefore likely to be equal. Their mean leverage ratios are likely to be equal. Since both sectors offer an investor the same lower risk, either or both can be chosen for investment.

Therefore conclude that there is at least one training method with a different mean performance score relative to the other training methods.

By inspection, the lecture and audio-visual are the least effective lower mean scores , while on-the-job and the role-play methods are more effective with higher mean scores. Recommendation The training manager is advised to consider either on-the-job training or use role play methods The difference does not appear to be statistically significant. The population mean performance scores between the two training methods is likely to be the same. Both are likely to produce similar high mean performance scores.

In two-factor ANOVA, two categorical factors are used to explain possible differences between the observed sample means. It is constructed from the sample means of the various combinations of the different factor levels. Alternatively, its p-value 0. If Arts graduates are employed, they must be given intensive marketing training. Hence all switch devices are likely to have the same average dropped call rate. Factor: Interaction effect Since F-stat 4. By contrast, average rubber wastage of radial tyres is lowest on TAM3 3.

Correlation analysis measures the strength of the relationship between the two numeric variables used in the regression equation. There is no statistically significant relationship between x and y. The more the training received, the higher the output. This book. Enter your mobile number or email address below and we'll send you a link to download the free Kindle App.
