independent and dependent variables are terms used to describe properties of an experiment that are being tested and measured. For example, let's say you want to figure out how much water you should be giving to your plant. You have three of the same plants and plan to give them different amounts of water for the next month 1. Prepare a null hypothesis for this case study. 2. What is the independent variable? 3. What is the dependent variable?

To analyze the experiment used to determine the properties of an electron. In 1909, Robert Millikan performed an experiment involving tiny, charged drops of oil. The drops were charged because they had picked up extra electrons. Millikan was able to measure the charge on each drop in coulombs. Here is an example of what his data may have looked like. In Millikan's experiment, the charge on each drop of oil was measured in coulombs. Imagine the same experiment, but with...

Describe a ChIP-chip experiment. How were ChIP-chip experiments used to study the regulation of target genes by Dorsal? This ChIP-chip approach is a bit dated. Today one would likely conduct ChIP-seq analysis. What is ChIP-seq and how does it differ from ChIP-chip?

Choose the study design that best matches each statement described below. The study design may be used more than once or none at all. (24 points) Statement Study Design ____ Blinding or masking is used to control potential bias. Case-Control ____ Observational epidemiological studies, this design is cheaper and faster to conduct because of the usage of already existing data. Cross-sectional ____ Control groups can receive the current “standard” treatment or a placebo. Ecological ____ Data on exposure and outcome...

Describe a public health problem (infectious/chronic/social), state a hypothesis and design a simple epidemiologic study to test it. You may choose either a cohort, case-control, or cross-sectional study, but justify why you chose it instead of the other study types. (Write a sufficient amount to demonstrate that you understand the question. For sample calculations, show your work or state the software used.)
