Normal type

in this experiment in order to see if there is a difference in the two population means of stride length in the two different species, N. rattus and N. squamipes. This is because the boxplots appear to be roughly symmetrical, as well as, both normal quantile-quantile plots look roughly linear. Considering two-sample t-procedures are quite robust to violations of the normality assumption, the t-procedure will likely perform well in this scenario. It is important to note that the second…

-Four Day School Week- I bet you would love a four day school week, but is it unhealthy ? Yes actually it is very unhealthy for us and I will tell you why.

Problem Statement A case study was conducted by a manufacturing company, Ace Inc., that specializes in circuit boards used in security devices. The study aims to determine basic math competency of its production line workers. A random sample of 71 production line employees were chosen for the survey and the test data results were collected accordingly. The resulting data also includes whether each employee in the sample took a statistics course or not. Ace would like to examine this data in…

possible mistakes. Beside, repeated trials can also repeated to give more data for analysis. (ii) Why do we need to complete checks on the data (identify errors etc)? To ensure the validity of the test. Validity is the absence of bias. There are three types of error in this reaction time test, namely direction error, anticipation error and timing error. -Direction error means that the reacting movement is not on the same side as the target. Such na unstandardized response can’t truly reflect…

When it comes to individual, everyone has different levels of ability to deal with memory. In reality, you will find many women complaining that their husbands or boyfriends tend to forget their birthdays and anniversaries; and men always explain that they have bad memories. So, is it true that women have a better memory than men? Dose gender affect memory? The evidence shows that gender dose affect memory. In fact, men and women are equally affected by short-term memory loss. Nevertheless,…

Abstract The value for the acceleration of gravity was measured in this report through the investigation using three different methods, each varying in accuracy, to calculate the period of a pendulum. The period was measured by repeatedly timing the time it took for the pendulum to return to its original position once it was swung from a certain point (for the first method one oscillation was timed, however in the second and third ten oscillations were timed and the overall time was divided by…

Being successful in life is not always easy because of the different perspectives that success can be achieved. With many theories out there on success, it is hard to figure out what is needed to be done to gain success in everyone’s life since there are many different beliefs out there that can lead to it. In the book “Outliers” by Malcolm Gladwell, there are numerous theories that are covered with examples of successful people that clearly show how success can be done in not just one way but…

To What Extent do IQ Tests Effectively Measure Intelligence? Introduction Albert Einstein, a famous theoretical physicist, once said that “the true sign of intelligence is not knowledge, but imagination.” While scholastic aptitude can play a large role in determining one’s intelligence, creativity is also a major factor. IQ tests, or intelligence quotient tests, are supposed to measure intelligence, but due to their ability to measure creativity, their accuracy is highly debated. According to…

Normalizing the Function of Autistic Children Wei Chi Chang Arizona State University  Normalizing the Function of Autistic Children Despite the fact that Lovaas (1987) claimed that the result indicated early intensive behavioral therapy would be efficient and beneficial, Schopler, Short, and Mesibov (1989) criticized the study by pointing out three major flaws— subject selection bias, adequacy of the control group, and inappropriate outcome measures. The subject selection bias was…
