The assignment involves several data analysis tasks based on various datasets, including a community Windshield Survey, bus maintenance data, survey of guest dessert ordering habits, and bank customer analysis. Each task requires the application of statistical concepts such as measures of central tendency, variability, data visualization, and interpretation of relationships between variables. The overarching goal is to analyze, interpret, and report findings based on these datasets to inform community health planning, operational efficiency, marketing strategies, and banking insights.

Community Windshield Survey Analysis

The Windshield Survey provides a snapshot of resources, services, safety, and social cohesion within a neighborhood located at 15019 Benfer Rd, Houston, Texas. Key community assets include proximity to healthcare facilities such as Walgreens Pharmacy (2.5 miles away), First Texas Hospital of Cy-fair (3.9 miles), and dental practices like Prestigious Smiles Family Dentistry (2.3 miles). Essential services like banks, veterinary clinics, and pet stores are also accessible within a few miles, fostering convenience for residents.

The social infrastructure is represented by organizations such as Champion Forest Baptist Church, Hardy Senior Center, and community service providers like lawn, housekeeping, and neighborhood assistance apps. The presence of a senior center offering both physical and mental activities highlights opportunities for engagement among older adults, promoting health and social well-being.

Public safety and transportation are supported by entities like the Klein Volunteer Fire Department, Harris County Constables, and services such as Uber, Lyft, Taxi, and MetroLift. While Houston’s overall crime rate is high at 52, local perceptions of safety indicate that neighbors are friendly and helpful, implying a relatively safe environment for residents.

Access to pet care and community resources indicates a neighborhood that supports a variety of needs, from health to safety to social connectivity. These insights are useful for public health planning, social services, and community engagement strategies.

Bus Maintenance Cost Analysis

The Lincolnville School District bus data offers insights into operational costs, which can be analyzed through measures like mean, median, range, and standard deviation. The clustering of maintenance costs around a particular value suggests the typical expense level, while the range indicates the variability. A high standard deviation would suggest significant variability in costs, potentially highlighting outliers or maintenance issues.

Calculating the mean maintenance cost provides the average expenditure, whereas the median indicates the middle point of the data, which often better represents typical costs in skewed distributions. The comparison between these two shows whether costs are symmetric or skewed towards higher or lower values.

Using the data, approximately 95% of maintenance costs would fall between two values determined by the mean plus or minus two standard deviations, assuming a roughly normal distribution. Outliers, identified through box plots, indicate buses with unusually high or low costs, which may warrant further investigation.

Relationship Between Gender and Dessert Ordering

The survey data on guests’ dessert choices involves categorical variables: gender (male or female) and whether dessert was ordered (yes or no). The level of measurement is nominal because categories are used without intrinsic ordering. The data is summarized in a contingency table, commonly called a cross-tabulation or crosstab.

The evidence from the table can suggest if men are more likely to order dessert than women by examining the relative frequencies and percentages. A higher proportion of males ordering dessert compared to females indicates a possible association, but statistical tests like chi-square would be required for confirmation.

Bus Data: Age Group and Maintenance Cost Analysis

Classifying buses into age groups (new, medium, old) allows for examining how maintenance costs vary with age. The median maintenance cost ($4,179) divides the data into low and high maintenance categories. A box plot provides a visual summary, showing the minimum, first quartile, median, third quartile, and maximum, as well as potential outliers.

Analyzing the contingency table reveals relationships between bus age and maintenance cost categorization. For example, a higher percentage of old buses with high maintenance costs suggests a positive association. Conversely, if maintenance costs are evenly distributed across age groups, the relationship may be weak or non-existent.

Bank Customer Data Analysis

The analysis of 60 bank customers includes descriptive statistics of checking account balances, such as mean, median, range, and standard deviation. Calculating these metrics per branch (Cincinnati, Atlanta, Louisville, Erie) can reveal differences in customer profiles across locations.

The clustering of account balances indicates typical customer wealth, while the presence of many with over $2,000 suggests a segment with substantial savings. The comparison of means and medians helps identify skewness: a higher mean than median indicates right-skewed data with some high-value accounts pulling the average upward.

Finally, insights about the usage of ATMs, debit cards, and other services are crucial for understanding customer engagement and informing marketing strategies. Altogether, these statistical measures help craft a comprehensive profile of the bank’s clientele.

Conclusion

Across all datasets, the consistent application of descriptive and inferential statistics—including measures of central tendency, variability, data visualization through box plots, and contingency tables—yields actionable insights. These insights support community health planning, operational efficiency, marketing strategies, and banking services optimization. Accurate interpretation of data and clear reporting enable stakeholders at various levels to make informed decisions, ultimately improving service delivery and community well-being.
