For this assignment, you participated in an online experiment on facial recognition. Using the data that I gave you and your statistics from the analysis, you will write a short lab report (2-3 pages) in APA style consisting of an Introduction, Method, Results, Discussion, and References.
Doing the experiment online is only to give you an idea of how the experiment works. You will write the mini lab report as if you were the researcher who conducted the experiment.
You may use this article by Rehman and Herlitz (2007) as a reference in your report: Facial Recognition Article
Here is the grading rubric for this report: Mini Lab Grading Rubric

Example 1.8. Fix a domain D, and let V be the set of all
functions f(t) defined (f + g)(t) = f(t) + g(t) Then V is a vector space as well, the axioms are verified similarly to those for Pn. |
Verify that V in the previous example satisfies the axioms for a vector space.

A speed field; It is defined by V(u,v)=(V1/L)(-xi+yj) , here V1 and L are fixed. This flow is 2 dimensional and stable.
(a)In which position in the flow area does the velocity equal the velocity V1? Make an outline of the speed field by drawing arrows for x>=0 , these arrows should represent fluid velocity in representative positions.
(b)Draw the flow line. (dx/u=dy/v)

Two 2.3 kg bodies, A and B, collide. The velocities before the collision are v → A = ( 34 i ̂ + 29 j ̂ ) m/s and v → B = ( 19 i ̂ + 1.6 j ̂ ) m/s . After the collision, v → A ′ = ( 4.0 i ̂ + 12 j ̂ ) m/s . What are (a) the x-component and (b) the y-component of the final velocity of B? (c) What is the change in the total kinetic energy (including sign)?

7/ The results of an experiment on the effects of sleep training on sleep quality showed that participants who received eight sessions of sleep enhancement training had longer sleep duration and better sleep quality than participants who did not receive the training. This led the researchers to conclude that an eight-week sleep enhancement training program is effective for improving sleep quality. What advantage of experimental research does this demonstrate? Multiple Choice Question Experimental research helps establish cause and effect relationships. Experimental research reviews media (e.g., old texts, pictures) to explore patterns in behavior. Experimental research allows the researcher to serve as a participant in the study. Experimental research uncovers as much as possible about a single person or situation. 8/ A research team designed a study of parenting style that included three groups: parents in their 30s with preschool-age children (2-5), parents in their 40s with children ages 6-11, and parents in their 50s with adolescents ages 12-18. This design is considered by the researchers to be less-time consuming and expensive than other potential designs, but they acknowledge the limitation of having only one measurement of parenting style for one point in time. As such, they cannot conclude that changes between parent groups indicate changes with age over time. Which research design does this describe? Multiple Choice Question Cross-sectional research design Cohort sequential research design Sequential research design Longitudinal research design 9/ College students are often recruited for research studies of young adult development, but this is often discussed as a limitation of those studies. How do you explain this? Multiple Choice Question It is an ethical violation to recruit college and university participants without their parents’ consent. College students are not randomly selected from the larger population, and they may not represent all young adults in our society. It is more difficult to get IRB approval for studies involving college and university students. University students tend to have higher rates of attrition compared to non-university students. 10/ A researcher who studies language development and tracks the rate at which toddlers learn new words is interested in which domain of human development?
