Prior to conducting any scientific investigation you need to learn as much as you possibly can about the biology of the organism in question To learn about the biology of an organism you would first consult textbooks and scientific journal articles to learn what is known about the organism This knowledge can give you a starting point for your research and provide direction of how to address your questions For some organisms c g fruit fly Drosophila melanogaster there is a large body of literature that covers everything from behavior and ecology to physiology and anatomy to genetics and evolution For other organisms much less is known This semester you will be asked to conduct scientific investigations on your own You will conduct an experiment collect and analyze data and report your findings in the form of a scientific research paper The first few labs are designed to provide you with the tools to complete these assignments The first step however will be to familiarize yourself with locating reading and interpreting scientific literature As a scientist it is very important to not only use these resources to help you with your experimental design and background on your research topic but also to communicate your own results If I conduct research in my lab but never tell anyone about it guess what It is like it never happened So I must communicate my findings to other scientists This is most often done in the form of peer reviewed scientific articles The goal of this exercise is to learn about a few of the resources available to you for finding scientific literature and to familiarize yourself with the various ways in which scientific articles are formatted each one is different Type your answers below each question or as instructed by the question Your answers should be color coded either blue red or purple to make your response obvious to your instructor Each response blank space is worth 0 5 pts for a total of 10 pts 1 There are two types of resources that can be used and are helpful Please do a Google search and define each of the terms below a Primary Literature

An amusement park studied methods for decreasing the waiting time minutes for rides by loading and unloading riders more efficiently Two alternative loading unloading methods have been proposed To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride a factorial experiment was designed Use the following data to test for any significant effect due to the loading and unloading method the type of ride and interaction Use a 0 05 Method 1 Method 2 Roller Coaster Source of Variation Factor A method Factor B ride Interaction Error Total 40 42 50 52 Sum of Squares SSA SSB Step 1 This is a two factor factorial experiment since the amusement park has collected data for the different methods of loading and unloading passengers and also different types of rides Let factor A be the method of loading and unloading riders and let factor B be the type of ride The ANOVA table for this experiment will have the following form SSAB Type of Ride Screaming Demon SSE 53 45 52 42 Degrees of Freedom a 1 b 1 a 1 b 1 ab r 1 Log Flume SST 07 1 abr 1 50 46 45 47 Mean Square MSA MSB MSAB a MSE SSA a 1 SSB b 1 SSAB 1 b 1 SSE ab r 1 F F F F MSA MSE MSB MSE MSAB MSE
