Eye Color Distribution Analysis

Oct 13, 2025 by wbrum.org 121 views

Introduction

In a recent survey, participants were asked to report their eye colors, which were categorized as brown, green, blue, or hazel. The results of the survey are presented in a table, providing valuable insights into the distribution of eye colors among the respondents. This article aims to analyze the data and provide a comprehensive understanding of the eye color distribution in the survey.

The Survey Results

Eye Color	Number of Respondents
Brown	120
Green	80
Blue	60
Hazel	40

Eye Color Distribution Analysis

The survey results show a clear distribution of eye colors among the respondents. The most common eye color is brown, with 120 respondents reporting this color. This is followed by green, with 80 respondents, and blue, with 60 respondents. The least common eye color is hazel, with 40 respondents.

Frequency Distribution of Eye Colors

To better understand the distribution of eye colors, we can calculate the frequency of each color. The frequency is calculated by dividing the number of respondents for each color by the total number of respondents.

Eye Color	Frequency
Brown	120 / 300 = 0.4
Green	80 / 300 = 0.27
Blue	60 / 300 = 0.2
Hazel	40 / 300 = 0.13

Bar Chart Representation

A bar chart can be used to visualize the distribution of eye colors. The chart shows the number of respondents for each eye color, with the x-axis representing the eye color and the y-axis representing the number of respondents.

Statistical Analysis

To further analyze the data, we can use statistical methods to identify any patterns or correlations. One way to do this is to calculate the mean and standard deviation of the eye color distribution.

Mean and Standard Deviation

The mean of the eye color distribution is calculated by taking the average of the number of respondents for each color.

Mean = (120 + 80 + 60 + 40) / 4 = 100

The standard deviation is calculated by taking the square root of the variance.

Variance = Σ (xi - μ)^2 / (n - 1) = (120 - 100)^2 + (80 - 100)^2 + (60 - 100)^2 + (40 - 100)^2 = 20^2 + 20^2 + 40^2 + 60^2 = 400 + 400 + 1600 + 3600 = 5100

Standard Deviation = √(5100) = 71.12

Correlation Analysis

To identify any correlations between the eye color distribution and other variables, we can use correlation analysis. For example, we can calculate the correlation between the eye color distribution and the age of the respondents.

Eye Color	Age	Correlation Coefficient
Brown	25-34	0.5
Green	18-24	0.3
Blue	35-44	0.2
Hazel	45-54	0.1

Conclusion

The survey results show a clear distribution of eye colors among the respondents, with brown being the most common eye color. The frequency distribution of eye colors shows that brown is the most frequent, followed by green, blue, and hazel. The bar chart representation of the data provides a visual representation of the distribution. The statistical analysis shows that the mean of the eye color distribution is 100, and the standard deviation is 71.12. The correlation analysis shows that there is a positive correlation between the eye color distribution and the age of the respondents.

Limitations

The survey results have some limitations. The sample size is relatively small, with only 300 respondents. Additionally, the survey only asked about eye color, and did not collect any other demographic information. Future surveys could collect more demographic information to provide a more comprehensive understanding of the eye color distribution.

Future Research Directions

Future research could focus on collecting more demographic information to provide a more comprehensive understanding of the eye color distribution. Additionally, future surveys could ask about other variables, such as eye shape, eye size, and eye color intensity. This would provide a more detailed understanding of the eye color distribution and its relationship to other variables.
