Drawing skills and gender
The hypothesis that female participants are better in their drawing skills than male participants is proven false.
The earliest known drawings were made by cavemen during prehistoric times on the walls of stone caves. Nowadays, drawings are done on paper, canvas or leather. Drawings that are used in commercial advertisements or produced as artistic masterpieces can be sold for very high prices. Computer art and illustration is becoming increasingly popular as input devices such as pressure-sensitive drawing tablets become cheaper and better in quality. Software such as AutoCAD are able to produce not only two dimensional drawings but also three dimensional drawings as well.
Repeat the experiment to compare the ability of male and female participants in painting.
Try to perform the experiment using different age groups to determine the effect of age on drawing skills.
