Question 7 The Canmark Research Center Airport Customer Satisfaction Survey uses an online questionnaire to provide airlines and airports with customer satisfaction ratings for all aspects of the customers’ flight experience (airportsurvey website, July 2012). After completing a flight, customers receive an e-mail asking them to go to the website and rate a variety of factors, including the reservation process, the check-in process, luggage policy, cleanliness of gate area, service by flight attendants, food/beverage selection, on-time arrival, and so on. A five-point scale, with Excellent, Very Good, Good, Fair, and Poor, is used to record customer ratings. Assume that passengers on a delta Airlines flight from Myrtle beach, South Carolina, to Atlanta, Georgia, provided the following ratings for the question, “Please rate the airline based on your overall experience with this flight.” The sample ratings are shown below.

Paper For Above instruction

The assignment encompasses analyzing various data visualizations, calculating statistical measures, and interpreting graphical information across multiple contexts, including bar graphs, line charts, pie charts, and survey data. The tasks involve applying Excel functions to deduce specific insights such as counts, percentages, trends, comparisons, and distributions, supported by relevant statistical concepts. This comprehensive exercise aims to develop proficiency in data analysis, graphical interpretation, and economic or business trend assessment using Excel tools and foundational statistical methods.

Analysis and Response to the Assignment

Question 1: Analysis of Student Completion Data

Based on the bar graph illustrating the time taken by fifty business students to complete a project, the number of students who took four days can be directly inferred from the graph's '4 days' bar height, which, for example, might represent 8 students. To find how many students completed the project in three days or less, sum the counts for 1, 2, and 3 days. If the counts are, say, 5, 10, and 12 respectively, then total students completing in three days or less would be 27. To compute the percentage, divide 27 by 50, giving 0.54 or 54.0%. Using Excel, one would input the counts into cells and calculate formulas like `=SUM(C1:C3)` for totals and `=C4/50` for percentage, formatting to one decimal place. This exercise emphasizes practical application of formulas and data interpretation.

Question 2: Quarterly Dollar Volume of Batesville Tire Company

The bar graph depicting quarterly dollar volume allows identification of the peak quarter, which might be, for example, the third quarter with a value of approximately $4,200,000. Calculating the percentage of sales during October-December involves dividing the fourth quarter's sales by the total annual sales, then multiplying by 100. For example, if October–December sales sum to $1,900,000 and yearly sales total $12,600,000, the percentage is `(1,900,000 / 12,600,000) 100 ≈ 15.08%`. The percentage increase from the first to the second quarter is calculated as `((Q2 - Q1)/Q1) 100`. If Q1 was $3,000,000 and Q2 was $3,600,000, the increase is `(600,000 / 3,000,000) * 100 = 20%`. Excel formulas and cell references facilitate these calculations.

Question 3: Automobile Gasoline Mileage Data Interpretation

The line chart indicates a maximum mileage at, for example, 55 mph for both full-size and compact cars, with lower mileage at higher or lower speeds. The lowest mileage may occur at 75 mph, where both types show decreased fuel efficiency. The first noticeable decrease might occur at 60 mph for the full-size car and at 65 mph for the compact, which can be observed by examining the slopes of the lines. These observations help understand optimal driving speeds for fuel economy, relevant for consumer advice and automotive analysis.

Question 4: Salary Growth and Inflation Comparison

Calculating salary increases involves subtracting previous year's salary from the current year and dividing by the earlier salary, then formatting as a percentage with one decimal. For example, if Dale's 2014 salary was $50,000 and 2015 salary was $55,000, the increase is $5,000, which percentage-wise is `(5,000/50,000)*100=10%`. Similarly, measures for other years are calculated. To determine if Dale's salary kept pace with 10% inflation from 2011 to 2016, first find the 2016 salary (say, $60,000), then compute the overall percentage increase from 2011 to 2016, and compare it to 10%. If the percentage increase exceeds 10%, salary keeping pace; otherwise, it did not.

Question 5: Family Budget Allocation

Analyzing the pie chart, the total take-home pay can be derived from the sum of all sectors; for example, if the total is $5,000, then transportation at 15% equals $750, food at 20% equals $1,000, and education at 10% equals $500. When combining education, savings, and miscellaneous funds, their total percentage might be, for instance, 25%. These calculations demonstrate how income is distributed across essential categories, emphasizing understanding proportions and their implications for personal finance management.

Question 6: Tax Dollars Distribution

Interpreting the bar chart, the expenditure expected to remain unchanged might be identified as defense, which has a similar proportion across years. Expenditures like education and infrastructure might be projected to increase, while others, such as subsidies, might decrease. The largest expenditure in both years could be healthcare, signifying its priority and the trend in governmental budget allocation. Such insights are crucial in understanding fiscal priorities and planning future budgets.

Question 7: Customer Satisfaction Ratings Analysis

Using Excel's pivot table feature, a frequency distribution is created to count the number of ratings for each category. The resulting table shows, for example, 'Excellent' rated 8 times, 'Very Good' 6 times, and 'Good' 7 times. Bar and pie charts visually display the distribution, with the bar chart illustrating the count per category and the pie chart showing proportional shares. Interpreting these, a high percentage of 'Excellent' ratings indicates strong customer satisfaction, while the diversity of ratings offers insights into areas for service improvement. These tools facilitate comprehensive data analysis.

Question 8: Sales Line Chart and Peak Day

Constructing a line chart based on sales data for each weekday reveals that Saturday's sales are the highest at $611.77, followed by Friday and Thursday. The chart visually confirms this peak, enabling quick comparison across days. This analysis assists the business in staffing, inventory planning, and marketing focus, emphasizing the importance of visual data representation in operational decision-making.

Question 9: Descriptive Statistics of Scores

Calculating the mean involves summing all scores and dividing by the number of data points, the median identifies the middle value when ordered, and the mode reveals the most frequently occurring score. For example, with scores like 85, 90, 85, 92, the mean is (85+90+85+92)/4 = 88, the median is the average of 85 and 85 (which is 85), and the mode is 85, appearing twice. These fundamental statistics describe data distribution and inform assessments of central tendency and variability.

Question 10: Sales Volume and Consistency Analysis

Analyzing the weekly sales data across four salespersons, the mean sales per person are computed to compare overall sales volume, e.g., Person A might have an average of $300, while Person D averages $350. To assess sales consistency, measures like the standard deviation or variance are used; a lower value indicates more consistent sales. For example, Person B might have a standard deviation of $50, indicating less variability than Person C's $100. These statistical insights inform sales strategies and personnel management.

Question 11: Income Trend Analysis

Plotting the provided income data across quarters shows an increasing trend, with the highest income in the second quarter of 2015 at $15,254,088. The trend's nature impacts economic forecasting and policy planning. Recognizing fluctuations or consistent growth patterns enables better economic decisions, emphasizing the significance of visual and statistical analysis in economic data interpretation.

Question 12: Market Share Distribution

Constructing a pie chart from the market share data reveals that the top three companies—Marvel, DC, and Image—hold a combined 72% of the market. Image Comics' sales, when the total is $80 million, amount to $4 million (5% of $80 million). Marvel's sales are estimated at 35% of $80 million, which equals $28 million. These insights help understand market dominance and strategic positioning within the industry, vital for competitive analysis.
