Exercise: Data Explorer1) Read the adult.csv file by executing the CSV Reader node2) Inspect the properties of the data with the Data Explorer node- How many different native countries are represented in the data? 40 countries3) In the interactive view, exclude the nominal columns that contain missing values- Which of the nominal columns contain missing values? How many missing values each? * native-country (583 missing values)* workclass (1835 missing values)* occupation (1842 missing values)Note! The Data Explorer node is part of the KNIME JavaScript Views (Labs) Extension Exercise: Scatter Plot and Composite View1) Read the adult_w_commute.table file by executing the Table Reader node2) Assign colors to the rows based on the marital status3) Draw a scatter plot of hours per week vs. commute time- Do you observe any particular relationship between these two columns?* There is a slight positive correlation between "hours per week" and "commute time".- What can you say about the marital status of people who work <25 hours per week andcommute the most? These individuals have a "never-married" marital status.4) Create an interactive table that displays the data. Use the Table View node.5) Encapsulate the Scatter Plot and Table View nodes into a component. Open thecomponent's interactive view.6) Switch to the mouse mode "Select" in the scatter plot view and select the data points with<25 working hours and >120 min commuting time7) Show only selected rows in the interactive table- What is the native country of the selected data points? All four individuals are from the UnitedStates.
