After conducting her survey, Dr. Aguilera collected quantitative data about the relationship between the following variables. Here are <em>the appropriate conclusions she could make</em>:
<u>The correlation coefficient -.64 indicates medium to strong correlation between anxiety and academic performance.</u> It means that a significant proportion of students who reported that they suffer from anxiety also reported lower academic performance. <u>This relationship may imply causality but does not prove it.</u> Further research with more appropriate methodology would be necessary to identify the causality of poor academic performance and other factors (variable) would have to be taken into account.
<u>Dr. Aguilera’s study showed no correlation between hours sleeping per night and academic performance</u>. <u>Meanwhile, it does not prove that there is no causal relationship.</u> Aguilera should have concluded that the questions in her survey do not ask about hours sleeping at day time.<u> She could present a hypothesis that students who compensates for little hours sleep at night with long day time naps do not demonstrate poor academic performance and investigate it with a new study.</u>

With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. In a solid, the particles pack together as tightly as possible in a neat and ordered arrangement.
