October 13‚ 2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden

T-test for Two Independent Samples * This test is used when only two unrelated groups are being compared and the measurements are either interval or ratio. The two groups may or may not have the same number of samples. * The t-test for two independent groups involves testing whether or not there is a significant difference between the population means of the two groups. Consider a study wherein the effectiveness of banana leaves as an organic wrapper was compared to that of aluminum foil

Virtual Reality in a Real Physical World Carla B October 29‚ 2012 The concepts of virtual reality have been around for quite some time. In fact‚ researchers have studied ideas of the three-dimensional world since the late 1950s. The ideals of virtual reality did not surface into our society until the late 1980s. Today‚ virtual environments are used in many different capacities. In this paper‚ research will show the positive impacts of virtual reality when it is applied to sports training‚ physical

effectiveness of global virtual teams and their means of communicating versus the effectiveness of face-to-face communication in non-global virtual teams. In doing so it will also serve to provide a basic understanding of the importance of communication within teams as well as what global virtual teams are. Previously written journals in this field of study will be consulted to add depth and validity to the topic of discussion. The strength and weaknesses of communication in global virtual teams as well as
