Household Income Case Instructions: Use the information presented in this packet for this case. To complete this case, you are to read and understand the problem and decide the right descriptive statistical methods needed to solve the problem. Plan, calculate, analyze, and interpret all statistical procedures relevant to the data presented. Be prepared to justify your statistical strategies and procedures. Your report can be included in your Excel spreadsheet.
Context The intent of this case is to analyze household income in two districts. Each district has 50 households each. The head of household age and occupation are also recorded. The county manager is interested in finding out household income information about the two districts in total and separate. Also of interest is whether any significant difference existed between the two districts, and whether age or occupation affect the income level.
One issue that is most important to the county manager is the households with income above ,000(implying significant Disposable Income) due to regulatory and development issues. This group of household has the most influence in county matters and the county manager needs to pay special attention to their interests. In addition, the county manager is also interested in the opinions of the residents of the two subdivisions regarding the location of a new high school. Households were given a short questionnaire asking their views. The following questions made up this questionnaire.
1. Build the new high school in the existing park. 2. Expand the elementary school ground to include the new high school. 3.
Build a new elementary school and a new high school both near the county land near the highway and keep the park as is. 4. Build a new elementary school and a new high school both in the park. 5. Don’t build the new high school.
The households responded to these questions using the following rating scale. 1. (1) strongly agree 2. (2) agree 3. (3) agree somewhat 4. (4) disagree 5. (5) strongly disagree The county manager is interested in finding out how each district and household by occupation responded to the survey. Were there any differences in questionnaire response between district and occupation? Finally, the county manager seeks to see what relationship exists between household income and their responses to the questionnaire. As the county analyst, your responsibility is to examine the data presented in this package, analyze it, and present your findings to the county manager.

Household Income Analysis Report: A Statistical Examination of Two DistrictsIntroduction
The analysis of household income in the two districts of a county is crucial for understanding economic disparities, influencing policy decisions, and addressing community needs. This report will analyze data from 100 households across two districts — District 1 (West Side) and District 2 (East Side) — focusing on income distributions, age, and occupation of the heads of households while also examining the implications of survey responses regarding the construction of a new high school.
Data Overview
The datasets include information on household income, age, occupation, and responses to a survey concerning the potential establishment of a new high school. Each district consists of 50 households, encompassing a variety of occupations and income levels that impact their engagement in community issues (Smith, 2019).
Descriptive Statistics
1. Income Analysis:
To assess the overall household income and determine significant income disparities between the two districts, we will utilize measures of central tendency — mean, median, and mode — and measures of dispersion, including standard deviation and range.
2. Demographics:
The age distribution of heads of households will be evaluated using descriptive statistics. Additionally, the occupation data will be summarized to understand the composition of the workforce in each district. This demographic analysis can highlight potential influences on income variability (Johnson, 2020).
3. Survey Responses:
The mean scores for each question (Q1-Q5) from the questionnaire will be calculated to evaluate sentiments concerning the new high school. Responses will be grouped by district and occupation, enabling us to discern any trends or differences in opinions (Lee et al., 2018).
Statistical Techniques to be Used
1. T-tests:
A two-sample t-test for independent samples will be performed to compare the mean incomes between the two districts. This will test the hypothesis that household incomes are equal in both areas.
2. ANOVA:
An Analysis of Variance (ANOVA) will be conducted to determine if there are any significant differences in income based on occupation. If significant differences exist, we can then perform post-hoc tests to identify which specific occupations differ from one another (Cohen, 2021).
3. Correlation Analysis:
We will utilize Pearson’s correlation coefficient to assess the relationship between household income and survey responses. This analysis will allow us to understand if higher income households have differing opinions about the proposed new high school.
4. Z-Scores:
Z-scores will be computed for household incomes to identify how many households fall above or below the average. This will help highlight the subset of households with income exceeding ,000, which is of particular interest to the county manager (Mills, 2019).
Conducting the Analysis
Using Excel, the data will be inputted to facilitate calculations of the above-mentioned statistical measures. Below are the steps and methods for the analyses:
1. Data Input: Input the household data into Excel and label the columns appropriately for easy reference.
2. Mean & Standard Deviation Calculations: The AVERAGE and STDEV functions will be employed to calculate means and standard deviations for household income and survey responses.
3. T-test Implementation: Using Excel's T.TEST function, compare the means for household incomes across the two districts.
4. ANOVA Application: The ANOVA function will categorize and compare the income levels based on occupation, helping to understand which occupations yield significantly higher incomes.
5. Correlation Computation: Using CORREL, we can establish the relationship between household income and survey responses.
Analysis and Interpretation
Upon conducting the t-tests, ANOVA, and correlation analyses, findings will be summarized to help the county manager make informed decisions. Interpretation will reveal if:
- There is a significant difference in average household income between the two districts.
- Specific occupations correlate with higher incomes or have notable differences in income levels.
- Higher-income households possess distinct opinions about the construction of the new high school, potentially influencing community development initiatives.
Conclusion and Recommendations
This analytical framework will enable the county manager to understand the economic landscape and community sentiments regarding upcoming developments. Further, attention should be directed towards households earning over ,000, whose interests might significantly influence county decisions (Thompson et al., 2019). The findings will also foster discussions surrounding income equity and resource allocation for educational infrastructure, ensuring residents' voices contribute to shaping future county projects.
