Introduction

In this article, we will delve into the world of statistics and explore the weekly salaries of 9 employees of a small business. The salaries are given in dollars and are already ordered from least to greatest. Our goal is to analyze these data and gain insights into the distribution of salaries within the company. We will use various statistical methods to describe the data, identify patterns, and make inferences about the population.

The Data

The weekly salaries of the 9 employees are given below:

Salary	Frequency
631	1
691	1
766	1
773	1
830	1
844	1
902	1
985	1
1003	1

Descriptive Statistics

To begin our analysis, we will calculate some basic descriptive statistics, such as the mean, median, mode, and range.

Mean: The mean is the average of all the salaries. To calculate the mean, we add up all the salaries and divide by the number of employees. In this case, the mean is:

\frac{631 + 691 + 766 + 773 + 830 + 844 + 902 + 985 + 1003}{9} = 843.22

Median: The median is the middle value of the data when it is arranged in order. Since there are 9 employees, the median is the 5th value, which is 830.
Mode: The mode is the value that appears most frequently in the data. In this case, there is no mode, as each salary appears only once.
Range: The range is the difference between the highest and lowest values in the data. In this case, the range is:

1003 - 631 = 372

Visualizing the Data

To get a better understanding of the data, we can create a histogram to visualize the distribution of salaries.

import matplotlib.pyplot as plt
import numpy as np
salaries = np.array([631, 691, 766, 773, 830, 844, 902, 985, 1003])
plt.hist(salaries, bins=10, edgecolor='black')
plt.xlabel('Salary')
plt.ylabel('Frequency')
plt.title('Distribution of Salaries')
plt.show()

Interpretation

From the histogram, we can see that the salaries are distributed fairly evenly across the range. There are no extreme outliers, and the data appears to be relatively symmetric.

Inferences

Based on the analysis, we can make some inferences about the population.

The mean salary is $843.22, which suggests that the average salary for the employees is around $843.22.
The median salary is $830, which indicates that the middle value of the data is $830.
There is no mode, which suggests that there is no single value that appears most frequently in the data.
The range is 372, which indicates that the difference between the highest and lowest values in the data is 372.

Conclusion

In conclusion, our analysis of the weekly salaries of 9 employees has provided valuable insights into the distribution of salaries within the company. We have calculated descriptive statistics, visualized the data, and made inferences about the population. These findings can be used to inform business decisions and improve the overall well-being of the employees.

Future Directions

There are several future directions that this analysis could take.

Further analysis: We could perform further analysis on the data, such as calculating the standard deviation, variance, and skewness.
Comparison to industry standards: We could compare the salaries to industry standards to determine if they are competitive.
Identification of outliers: We could identify any outliers in the data and investigate their causes.
Development of predictive models: We could develop predictive models to forecast future salary trends.

Limitations

There are several limitations to this analysis.

Small sample size: The sample size is relatively small, which may limit the accuracy of the results.
Limited data: The data only includes weekly salaries, which may not be representative of the employees' overall compensation.
No control group: There is no control group to compare the salaries to.
No consideration of external factors: The analysis does not consider any external factors that may affect the salaries, such as location, industry, or company size.

Recommendations

Based on the analysis, we recommend the following:

Conduct further analysis: Conduct further analysis on the data to gain a deeper understanding of the distribution of salaries.
Compare to industry standards: Compare the salaries to industry standards to determine if they are competitive.
Identify and address outliers: Identify any outliers in the data and investigate their causes.
Develop predictive models: Develop predictive models to forecast future salary trends.
