Amazon 's Mechanical Turk ( M Turk ) Essay

The strengths of Pollastek et al’s (2012) study lie in the methods used for data collection. By utilizing a driving simulator to imitate potentially hazardous driving conditions, Pollastek et al (2012) ensured that the experiment was safely conducted. The driving simulator also allowed Pollastek et al (2012) to test participants in a controlled setting restricting the number of unknown

We will have both groups perform a driving test at 12:00pm to help reduce sunlight in the driver's eyes while maintaining good lighting for the course. A driving instructor will be placed in the car with the subject. They will record the scores of the drivers. No cell phones will be used this day because this is only to record the initial results. The next day we will set up the same course as yesterday but this time have the experimental group of drivers perform the course while being asked Trivial Pursuit trivia questions by our researchers. The control group will drive the course the same as the previous day. A driving instructor will remain in the car recording the results. With this set up, we have secured the independent variable as the one we want to test. The conditions remain the same every day for both groups except for one the one variable we are

In society, people base their life on intelligence. They do everything possible to get ahead in life. To get ahead, they cheat each other, back stab, and commit many sinful acts. Also, they educate themselves so they are capable of doing whatever is required of them. Society is trying to always make themselves smarter. Are they trying to change something that they have no control over though? Intelligence is something that everybody has, but is something that is developed over time. The development of intelligence has many items that play a factor. For instance, environment and heredity both play a role in developing a person's I.Q.

These experiments exposed its participants to an obvious emergency situation that required some sort of action. These participants were presented with this situation either individually or alongside a group of “participants” (typically recordings or those ‘in’ on the experiment).

The survey was posted online using crowdsourcing web service Amazon.com Inc’s MTurk. The full survey can be seen in Appendix 1. Responders are anonymous, however they are given a unique identifier by Amazon which allows us to identify if any user has taken the survey more than once. We used MTurk users with an approval rating of 85% or greater (meaning 85% of their previous work on the site had been considered good). These parameters were chosen to help improve data quality. Additional discussion of the use of mechanical turk and parameters used can be found in our previous work.

Everyday,either on social media or on a newspaper article there will always be that one story about someone taking a huge risk,such as:reporting news 73 year old woman climbs mount Everest. This is great news but for to rescuers it not,if that 73 year old women didn’t know what she was doing or what she was getting her into she could have seriously hurt herself and that also means rescuers would be in risk.I believe that people should not have the right for rescue services when they put themselves in danger because they signed up for this knowing what they were getting into and rescuers are also dying because of these incidents,.Think about what you're doing before you do it,you may risk someone else's for your own.

During the testing of which is more dangerous: drunk driving or using your cell phone while driving three experimental conditions were used during the hypothesis. One of those conditions was regular driving. They took two people of the different sex and tested their driving on a driving course without any influence being involved. The next condition was cell phone-driving; one of the experimenter’s used a cell phone to talk to the same two people. While talking to them on the phone he delivered three different tasks for them to do to assure they were distracted. The last condition was drunk driving; both experimenters drunk the same amount of beer and was given a breathalyzer test to assure the amount of alcohol was past the legal amount. They

However, when all the psychological methods presented in this chapters have their advantages and disadvantages, the most notable problem seems to be personal bias (researchers’ and participants’). After all, we are human and it seems inconceivable that all the personal biases could be taken into account in a psychological research. Too small a sample size of participants will not be able to reflect an entire population, but

To be born into this world with all of one’s five senses is a gift from God. I realized the value of this gift when my middle school class made a trip to Akruti, a school for mentally challenged children with special needs. To my discomfort and despair, I saw children who were facing difficulties in learning basic Math and English. That moment humbled me, as I recognized how fortunate I was to possess excellent skills in Math and Science.

In the process of conducting this experiment, I learned a lot and collected very interesting data. My hypothesis was, for the most part, incorrect, which could be accredited to the fact that this project had several weaknesses. The data this experiment was designed to collect can be very useful to scientists and psychologists if it was replicated on a larger scale. Overall, the project was very successful.

Many different questionnaires can give a broader range of data and reduces the chances of bias data. Using a survey in the experimental design for this study was a good choice because surveys allow a significant amount of data to be collected by researchers without spending an enormous sum of money, particularly if the participants take the survey online. The article didn’t specify how the researchers administered the surveys, but the cheapest and quickest way would be to send the surveys out through E-mail. Using surveys in this study also made the data incredibly easy to analyze. Using another experimental method, such a brain scan, would be more expensive and could require a scientist to interpret. Surveys also allow users to maintain anonymity, and thus reducing bias in the data. In my opinion, computerized surveys eliminate bias effectively because they give the best sense of obscurity. Anonymity also increases

According to Statistic Brain, “A total of about 751,931 non endangered species and 1,041 endangered species of animals are kept in zoos around the world ”. Many of the non endangered animals are capable of living in the wild by themselves, but the more time they spend in zoos the more they will forget about how to survive in the wild and they will also gain many other negative effects. Zoos are more harmful than helpful because they restrict animals to enclosed habitats, they weaken the animals primal instincts, and they cause the animals stress which lead to mental and physical health issues.

Stayer et al.(2006) compared two types of drivers which mobile phone drivers and drunk drivers. Alcohol has been used as a benchmark for assessing performance impairments including in aviation, fatigue and many more. Thus, it is good for the study to see the harmful effects of using mobile phone on driving performance by comparing it with the performance of drivers with a blood alcohol concentration at a legal limit. Other strength is Strayer et al.(2006) used repeated measure in the study. All of the forty participants need to participate in all of the conditions. This will exclude the effects of individual differences that could occur if two different people were used instead. Thus, the result of the study became more valid as the researchers can observe participants’ driving performance from three different conditions. The limitation of the study is the usage of driving stimulator in the experiment. Participants have not been exposed to the real danger as driving stimulator can control the condition. Thus, they might act in a different manner compared to a real life situation. Next, distractor vehicles were programmed to drive between 5% and 10% faster from the participants’ car. So, participants were prepared and used to that kind steady flow of traffic. It does not reflect real life situation where distractor vehicles will drive at any rate of speed. The distractor vehicles could be faster or slower than our car in real situation. Thus, the increased or decreased in driving performance can be question out because the speed of distractor vehicles has been set up rather than having normal speed of distractor

Forty five students from the University of Washington took part in Experiment 1, who were put into groups of various size. Each subject was shown seven films of traffic incidences. The clips were short fragments from road safety films which ranged in length from 5 to 30 seconds. After

This paper explores how experiments are conducted utilizing statistical analyses. As Goldstein (2015) explains, experiments are conducted for a variety of reasons. In many cases, experiments are conducted to advance the knowledge of certain behavior of subjects, some experiments are conducted for general purposes, and some are conducted in the acts of science. The Analysis of Variance (ANOVA) is a statistical test that helps researchers narrow the amount of time spent on determining the variance of two or more groups (Trochim & Donnelly, 2008). This paper analyzes the components and purpose of the ANOVA test in research.
