Techniques of data analysis

come up with a research question and explore it using the techniques of data analysis that we have described in class and explored in the labs. You will develop your own research question and answer that using data from the attached work safety data. You will perform all of the data processing and analysis steps performed using excel or any other software of your choice. Steps you will complete include:  Open the attached work safety dataset.  Combine and clean data, recode and prepare excel spreadsheets with the variables of interest  Change variable names and labels  Check for missing data types and variables  Code categorical variables in letters or symbols (age group, gender, incident cost, shift) into numerical variables.  Compute descriptive statistics (mean, standard deviation, median, minimum, maximum) for incident cost and day lost.  Compute frequencies for age group, gender, incident type and shift.  Perform histograms of incident cost and day lost.  Perform bar graphs and pie chart of age group, gender, incident type and shift.  Perform a scatterplot of incident cost (dependent variables) versus day lost (independent variable).  Compute a correlation between incident cost and day lost.  Perform a simple linear regression analysis between incident cost and day lost.  Perform a multiple linear regression between incident cost and day lost, age group, gender, incident type and shift.
