    Analysis of Socioeconomic and Demographic Variables: A Statistical Approach Using Descriptive, Hypothesis Testing, and Chi - Square Tests Based on the dataset provided, you are required to analyze and interpret the relationship between various continuous and discrete variables. You are expected to focus on the following: 1. Descriptive Statistics for Continuous Variables: o Wealth Score o Median School Years o Age For each continuous variable, calculate and interpret the following measures: • Mean • Median • Mode • Variance • Standard Deviation Provide a detailed explanation of the observed patterns and suggest what the distribution of each variable might look like based on the statistical measures (e.g., bimodal, normal, skewed). 2. Analysis of Discrete Variables:

    o Marital Status o Presence of Children o Gender Provide frequency tables and bar graphs for each of the discrete variables, and interpret the findings. Specifically, discuss the relationship between the categories within each variable and provide insights based on the count distribution. 3. T - test Analysis: Perform t - tests to determine if there is a significant difference between the means of the following pairs: o Wealth Score of Married vs. Single o Median School Years of Married vs. Single o Age of Married vs. Single o Wealth Score of Males vs. Females o Median School Years of Males vs. Females o Age of Males vs. Females For each t - test, state the null and alternative hypotheses, provide the test results, and interpret the findings. Be sure to include the p - value and explain whether the null hypothesis is rejected or not. 4. Chi - Square Test: Perform Chi - Square tests to examine the independence of the following pairs:

    o Marital Status and Wealth Score o Marital Status and Median School Years o Marital Status and Age o Gender and Wealth Score o Gender and Median School Years o Gender and Age For each Chi - Square test, state the null and alternative hypotheses, provide the test results, and interpret the findings. Discuss whether the null hypothesis is rejected or not based on the p - value. 5. Handling Missing Data: Discuss the potential impact of missing data on the accuracy of the statistical results. How can missing data influence parameter estimates and overall findings? Suggest methods to handle missing data in future analyses. Word Count Requirement: • Total word count: 800 - 1000 words

    Three continuous variables chosen are Wealth Score, Median School Years and Age. whereas, three discrete chosen variables are Marital Status, Presence of Children and gender. Continuous variables Wealth Score Variable mean median mode variance standard deviation Wealth Score 301.8376 299.01 490.46 8902.29564 94.35197741 Here, it is observed that mean is approximately equal to median. A nd mode is greater than mean and median. This gives me an idea that graph of Wealth score must be Bimodal . Mean is sum of all observations divided by total number of observations. Here, mean is 301.8376 implying that an average Wealth Score is 301.8376. The median in an ascending series is the value at which there are just as many values less than it as there are greater than it. Here median is 299.01 which is approximately equal to mean. Thus I can say that, half of the wealth score is more than 299.01 and that of other half is less than 299.01. Mode is the number which occur maximum number of times. Here mode is 490.46 implying wealth score of maximum number of people is 490.46 . The variance and the standard deviation are both measures of the spread of the distribution about the mean. The standard deviation measures how concentrated the data are around the mean; the more concentrated, the smaller the standard deviation. Standard deviation measures spread in the same physical unit as the original data. Standard deviation and variance is given in the table above. The high value of standard deviation implies that my mean is not much reliable.

    The frequency table for Wealth score is shown below: Bin Frequency 100 9 200 290 300 714 400 667 500 320 More 0 And the corresponding histogram is shown below It is observed that shape of the distribution of wealth score is Bimodal. That is it has 2 modes. The same is observed from numeric data. 0 200 400 600 800 100 200 300 400 500 More Frequency Bin Histogram Frequency

    Median School Years Variable mean median mode variance standard deviation Median School Years 13.26322 13.2 12 2.03052845 1.424966124 Here, it is observed that mean is approximately equal to median and also to mode. This gives me an idea that graph of Median School Years must be Normal. Mean is sum of all observations divided by total number of observations. Here, mean is 13.2 implying that an average Median School Years is 301.8376. The median in an ascending series is the value at which there are just as many values less than it as there are greater than it. Here median is 13.2 which is approximately equal to mean. Thus I can say that, half of the Median School Years is more than 299.01 and that of other half is less than 13.2. Mode is the number which occur maximum number of times. Here mode is 12 implying Median School Years of maximum number of people is 12. The variance and the standard deviation are both measures of the spread of the distribution about the mean. The standard deviation measures how concentrated the data are around the mean; the more concentrated, the smaller the standard deviation. Standard deviation measures spread in the same physical unit as the original data. Standard deviation and variance is given in the table above. The low value of standard deviation implies that my mean is reliable.
