Concept explainers
a.
To identify: The control and experimental groups in the mouse camouflage experiment.
Introduction: Experiments are designed to test the hypothesis. The data obtained from the experiments are often represented in the form of graph for easy comparison and analysis. Experiments and data analysis are part of scientific methods to test a good hypothesis.
b.
To identify: Independent variable and dependent variable.
Introduction: There are two types of variables in a controlled experiment that include independent and dependent variables. Independent variables are the ones that can be exploited by the researcher and that affect the dependent variables. Dependent variables are measured by the researchers.
c.
To explain: The reason why the results of the study is measured as the proportion of the attacks by the predator on the two different coat colored mice camouflaged in the two different colored surfaces, respectively, instead of the total number of attacks by the predator on the non-camouflaged mice.
Introduction: Variables of the experiment are qualitative and quantitative measures that include traits, conditions, or factors.

(cite at least one source)arrow_forwardWhat is the primary reason for randomizing group allocation in a randomized controlled trial (RCT)? Question 3 options: to create treatment and control groups of equal size to blind participants to their group allocation to evenly distribute known and unknown factors that may affect the outcome between groups to increase the treatment effect between intervention and control groupsarrow_forward
- An early study found that postal workers who worked in the office had higher rates of coronary heart disease than those who delivered mail on foot. The investigators concluded that physical activity is inversely related to risk of developing coronary heart disease. Sceptics disagreed, pointing out that the postal clerks were older than the postal carriers, and that age is a risk factor for coronary heart disease. This argument highlights the possible role of: -Chance? -Selection bias? -Recall bias? -Confounding?arrow_forwardFor each measure below, indicate which kinds of reliability would need to be evaluated. Then draw a scatterplot indicating that the measure has good reliability and another one indicating the measure has poor reliability. C. Psychologists measure how long it takes a mouse to learn an eyeblink response. For 60 trials, they present a mouse with a distinctive blue light followed immediately by a puff of air. The 5th, 10th, 15th trials are test trials, in which they present the blue light alone(without the air puff). The mouse is said to have learned the eyeblink response if observers record that it blinked its eyes in response to test trials. The earlier in the 60 trials the mouse shows the eyeblink response, the faster it has learned the response.arrow_forwardIdentify the type of behavior. 1) 2) Goose. Bees attracted to the smell of the flower and flying towards the scent. _: Once initiated, it will run to completion and this could be observed in nesting behavior of Graylag 3)_ : A genetically program form of learning during developmental stage. Example: sparrow babies learn how to sing exactly at the same frequency as the mother. But if the babies grow isolated from their mother, the singing frequency will be different. 4) A turtle draws its head back into its shell when its shell is touched. After being touched repeatedly, the turtle realizes it is not in danger and no longer hides. This is an example of 5) : A child might stop throwing tantrums after his/her favorite toy is taken away after each tantrums.arrow_forward
- What is the difference between the experiment's control group and controlling for confounding variables?arrow_forwardThe pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes?* nd 2 chool The proportion of DDT-resistant mosquitoes in a population remains constant due to O the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is intróduced to a rainforest. Over the next year, the finches show a death rate of…arrow_forwardThe α level in the context of reporting findings from a randomized controlled trial corresponds to the probability of concluding: Correctly that the treatment and control groups differ with respect to risk of outcome. That the treatment and control groups differ with respect to outcome when in fact they do not. Correctly that the treatment and control groups do not differ with respect to outcome. That the treatment and control groups do not differ with respect to outcome when in fact they do. That you don’t have sufficient information to present results.arrow_forward
- 1. 40 OT students were randomized into two groups and 40 nursing students were randomized into two groups. One of the OT groups and one of the nursing groups were given the opportunity to participate in a research project and present their data at an IPE conference. The other group of OT students and nursing students completed their normal course work. At the end of the semester the faculty measured all of their students’ knowledge about research design and confidence presenting information to others.
