Statistical hypothesis testing

Scientists use the same scientific method to follow steps (observation, hypothesis, and experiment) to have a better understand of the worlds; however, they make different hypothesis and approach the problem in their own ways to find solutions, therefore some of them have different results the order. 5. Concerns: a. I’m worried I cant remember all of the reactants and products…

The scientific method is a procedure that is used by scientists now and in the past, dating back to the seventeenth century. The scientific method consists of observation, measurement, and experiment, and the creation and testing of hypotheses. There are several steps and different components to the scientific method that will (hopefully) answer the scientists’ questions, by the completion of the experiment. There are countless different reasons as to why a scientist would use the…

(56 / 100) than those who did not listen to music (42 /100). However, the chi-square test of independence showed no significance. Therefore, the results support, but do not accept hypothesis three: Listening to music while studying will cause students to become less distracted. Also, they do not support or accept hypothesis one: listening to music while studying will cause students to become distracted more often, because the results showed minimal difference between distraction and lack of…

environment over the dry environment because they are used to living in moist conditions. If exposed to salty and neutral conditions, they will prefer the side with DI water because the soil pill bugs generally live in is closer to pure water. Statistical Analysis Ho: The pill bugs will be evenly distributed across the two different parts of the choice chamber. Ha: The pill bugs will not be evenly distributed across the two different parts of the choice chamber. The appropriate test is a…

Karl Popper, as part of his career long attempt to support empiricism in science, proposed a doctrine of falsification. This directly contrasts verification, a central theme to logical positivism. A claim is empirically verifiable if observation and experimentation produce statements which logically imply the truth of the claim. Popper rejected the logical empiricists' ideas given that “verificationism” does not allow for claims within a universal scope to be subject to verification.1 This is…

Science is what I live for. science is my life. I thought every thing could be explained through science or logic. But it could not explain one of the biggest incident in my life. It can't explain Amelia. Eisenstein.It was Eisenstein whose work built an interest for physics in me. I fell in love with his work, with his discoveries and inventions. I wanted to be like him.To Be a physicist. That is why i went to Germany for higher education at the age of 18. Usually people find hard or…

According to the IOP, Institute of Physics (2014), “A misconception can be defined as a view that does not fully coincide with the scientific view” (Hutchinz, 2014). It is said that Isaac Newton’s laws are there as a guideline to help with the understanding of science and to steer clear of misconceptions when it comes to the concept ‘force’. This concept is very difficult to teach. Misconceptions occur because people lack the ability to believe in the implications of these laws and to…

Due to the increased number of retractions in the psychology journals and release of the news story of a famed social psychologist fabricating data leading to more than 50 retracted papers in the recent years, there has been a lot of speculation and criticism surrounding the fields of psychology and social sciences. In light of this, a newer initiative called the Reproducibility Project at the University of Virginia reran 100 psychology experiments that were published in three leading psychology…

Although this is the first time I heard about the Toulmin model, the information resources helped me to understand how this model works. The Toulmin Model constructs or analyzes a persuasive argument. Its name provides from its creator Stephen Toulmin. The Toulmin Method breaks an argument into six essential parts (claim, evidence, warrant, backing, rebuttal, and qualifier) that weight and support points for both for and against the argument. The Toulmin Model provides an excellent method for…

A ball, and a feather dropped at the same height will hit the ground at the same time when placed in a vacuum space. This is because acceleration of motion is the same for both object, and in this experiment, we are going to calculate accelerated motion using inclined planes. In this experiment, we will see whether “distance traveled is directly proportional to the square of the time”, and “if speed of a falling object depend only on the height from which it falls”. This experiment will give us…
