## 这个project是用R语言分析纽约工作岗位的情况

Proposal of R Project

Introduction

For this project, I want to focus on jobs in New York. For this part, I will use real data source from the Official Website of New York State (https://data.ny.gov/City-Government/NYC-Jobs/kpav-sd4t). This data set includes job postings available on the City of New York’s official jobs site from 2013 to 2019.

Choosing this part to analyze is because getting job is an important decision for students who will graduate. Students usually spend too much time to writing their resume and preparing their interview. Good analytics can give them some advice about what kinds of jobs have more opportunities to apply. By analyzing what kinds of jobs have high demand in companies, we can predict demand in the future. For students who still need to declare major, this project can give them some guidance. Besides, this project can reflect the partial economic situation and the quality of job in New York. Changes of jobs’ types or numbers might reflect changes of New York. We can understand why these changes happen by analyzing the changes of jobs.

I decide to analyze four parts of jobs in New York, based on the dataset. First part is relative to job opportunities of each company. Second is about what kinds of jobs they provide, and which one has highest demand. Third is about some conditions of jobs, such as internal and external postings, part-time or full-time and so on. Fourth is based on locations of companies.

Research Design and Methods

The analysis of whole project is based on R. In this project, I will use R to make different tables and graphs. I also need to make some conclusions by what I got in R. Therefore, R is core method.

Step one,

I will explain more information of data to reader. It will help them having a general concept of dataset.

Step two,

I will think about five questions (maybe more in the projects) that I need to use R to analyze and give answers. Specifically, I will use R to get some tables which shows different variables I need to analyze.

1. How many jobs dose each company provide?
2. What is the location which has highest job opportunities?
3. Do companies prefer to provide internal postings?
4. What is the tendency of job offers in New York annually?
5. What kind of job has high demand in New York?
6. Where has more chance to get jobs? Where has less chance to get jobs?(Heat map)
7. What is the tendency of demand of jobs in New York?

Step three,

Based on the tables I get in step two, I will make some graphs. For example,

Step four,

According to step one to three, I will make a conclusion.
