So I went to using other variables trying to predict education_level but first, I had to make some changes to the used data as you can see I changed the column gender and education level one. Employees with less than one year, 1 to 5 year and 6 to 10 year experience tend to leave the job more often than others. Metric Evaluation : Three of our columns (experience, last_new_job and company_size) had mostly numerical values, but some values which contained, The relevant_experience column, which had only two kinds of entries (Has relevant experience and No relevant experience) was under the debate of whether to be dropped or not since the experience column contained more detailed information regarding experience. Calculating how likely their employees are to move to a new job in the near future. StandardScaler removes the mean and scales each feature/variable to unit variance. Question 3. for the purposes of exploring, lets just focus on the logistic regression for now. In our case, the columns company_size and company_type have a more or less similar pattern of missing values. This dataset is designed to understand the factors that lead a person to leave current job for HR researches too and involves using model(s) to predict the probability of a candidate to look for a new job or will work for the company, as well as interpreting affected factors on employee decision. This needed adjustment as well. to use Codespaces. Third, we can see that multiple features have a significant amount of missing data (~ 30%). Note: 8 features have the missing values. Scribd is the world's largest social reading and publishing site. Question 2. Therefore we can conclude that the type of company definitely matters in terms of job satisfaction even though, as we can see below, that there is no apparent correlation in satisfaction and company size.
