I know this is probably asking a lot but if someone can pull

I know this is probably asking a lot but if someone can pull this through for me that would be amazing:

The goal of this lab is to create a dashboard in JavaFX summarizing a large dataset. For the first assignment, use the 2015 CSV file for City of Vancouver property tax assessments:

http://data.vancouver.ca/datacatalogue/propertyTax.htm

Your dashboard should have displays for each of the following information:

Average property value and standard deviation for the entire data set.

Average house age and standard deviation for the entire data set.

Total house value change for the entire data set (current land value – previous land value).

Count the number of Commercial, One Family and Multiple Family Dwelling for the entire data set.

The maximum value, minimum value, and number of homes with house value by increments of $25000. For example, this could be a table, bar chart, or pie chart, which shows the number of homes with value from (thousands) 100 – 125, 125-150, 150-175, 175-200, etc all the way to the maximum first “bin” or interval that has 0 (this should be somewhere in the millions..)

The user should be able to double-click on any of the displays for items 1-5 to drill down to show more detail on the calculation. The next level of detail should be a stage with a ListView by street name, and then double-clicking on a given item should open another stage showing the calculation by postal code. For example, double-clicking on the property value should show a display of property values by postal code. Double-clicking on a given postal code should then show the property values by street name.

Marks:

Property value and standard deviation are shown properly                         +2

House age and standard deviation are shown properly                                +2

House value change is shown properly                                                         +2

Number of property types are shown properly                                             +2

House values histogram is shown properly                                                   +2

Double-clicking on items 1, 2, or 3 shows the calculation by street name, and then by postal code.                                                                                            +4

Create an HTML user guide with screenshots of your interface of where the professor should look to find the information for items 1-6. Also write 1 sentence explaining why you chose your chart type for displaying the information.         +2

Solution

For mean -

public double findMean(){
double mean = 0;
int sum = 0;
for(int index=0;index<list.size();index++)
sum = sum+(int) list.get(index);

mean = sum/2;
}

For Median -

public int findMedianValue(){
int median =0;
median = (int)list.get(Math.floor(list.size()/2));

return median;
}

For variance -

SUM((x[i] - mean(x)) ^2) / (n-1)
(i = 1..n)
