Quantile analysis

Analysis performed including anonymous classes:

Location	Event type	Q1	Q2	Q3
class	attributes	0	0	3.000000
class	cohesion	-1	0	0.000000
class	comments	-	-	-
class	complexity	0	0	5.000000
class	complexityRatio	0	0	1.236455
class	coupling	-	-	-
class	instructions	2	7	26.000000
class	methods	1	1	4.000000
interface	numberOfMethods	1	1	3.000000
method	calls	-	-	-
method	chainLength	1	1	1.000000
method	complexity	0	0	2.000000
method	instructions	1	2	7.000000
method	parameters	0	1	1.000000
method	switchStatements	0	0	0.000000

Also worth mentioning that we excluded anonymous classes in the second analysis.

After removing anonymous classes:

masters-thesis's Issues

Heading and subheadings

Write heading and subheadings.

Also for each section provide small description of what will be inside that section.
