Howdoes the inclusion of different explanatory variables impact the gender wage gap, and what doesthis imply for addressing salary disparities in the workplace? Provide a detailed interpretation ofthe results and suggest potential strategies for improving pay equity based on the findings.Word count requirement: 750-1000 words.

Salary of female employeesPage2of11******************************************************************************PurposeThis memorandum provides an analysis ofdependence of salary on other factors such asthe gender of employee,education level, job grade,age,experience level and many other relatedvariables.Specifically, we examined the relationship betweensalary and gender so as to analyzethe how the salary of female employees changes if othersaidfactors are taken into consideration.BackgroundThegender pay gap(also known asgender wage gap,malefemale incomedifference,gender gap in earnings,gender earnings gap,gender income difference) is thedifference between male and female earnings expressed as a percentage of male earnings,according to theOECD.TheEuropean Commissiondefines it as the average difference between men’s and women’shourly earnings. It is generally suggested that the wage gap is due to a variety of causes, such asdiscrimination in hiring,differences in education choices, discrimination in salary negotiations,differences in the types of positions held by men and women, differences in the pay of jobs mentypically go into as opposed to women (especially highly paid high risk jobs), and differences inamount of work experience, and breaks in employment.AnalysisObjectivesOur study sought to determinethe following:(1)The factorsor combination of characteristicsthat influences the salary structure of afemale employee.

Theadjusted R2for eachregression wasalsomonitored to determine whetheradditional variables mayhavebeensuperfluous.Reliabilityof the coefficientswasassessed by examining statistics such asp-values.Variablesfor which data wasavailableincluded the following:Variables Employed in AnalysisExplanatoryVariableUnitsAbbreviationFemale*1 or 0femaleAgeYearsAgeYears prioryearsyrspriorYears experianceYearsYrsexperEducation level1,2 or 3EduclevEducation level =i†1,2 or 3Index 1,2,3*Femalevariable with value1 means female and 0 means male.Education levelwith higher value indicating more education.ResultsThe analysis began with a review of scatter plots of Salary v. variables such as Age,female. While female alone (Figure 1) produced a low coefficient of determination (R2less than13%), Age(Figure 2) produced a slightly higher, though still weak explanatory relationship(17%) to Salary.
