The article “Why most published research findings are false” elaborates on why most recent research is not reliable. Research findings are assessed based on the study power, biasness, and connection between variables under study. In case field studies are less than required, the chance of the findings being wrong is...
Introduction The process of estimating a population parameter, unknown and fixed, from a sample statistic, known and random, is called statistical estimation. This process involves forming either a point estimate or an interval estimate. The former is a single numeric value, often referred to as the “best guess” at estimating...
Since their discovery, neutron stars have represented one of the most enchanting mystery for scientists. A recent article by Adam Mann suggests that the discovery made lately concerning the nature of neutron stars may reinvent the entire perspective on the subject matter. Though discovering the entire nature of the core...
The birth of a star is a truly spectacular occurrence that deservedly garners substantial attention. However, the recent gamma-ray explosion produced by a supernova represents a particularly exciting subject of discussion since it is bound to reinvent the current perception of how supernovas emerge in space (Xi et al. 2)....
As a reviewer, I would start by stating that statistical significance involves a statistic’s critical value. It helps determine whether the null hypothesis needs to be rejected or fails to get rejected. On the other hand, meaningfulness implies a statistic’s efficiency and applicability to the real world (Laber & Shedden,...
Linear regression, known for its common use in statistics, is a model showing the relationship between predictor (dependent) variable and response (independent) variable. Simple linear regression is the most basic for linear regression, quantifying the relationship between predictor and response variables. When dealing with such relationships, analysts often use correlation...
Introduction Nicholas Copernicus was an astronomer and mathematician who was able to make a model of the universe during the Renaissance. Copernicus wrote his theory in the work De revolutionibus orbium coelestium 1543 (On the rotation of the celestial spheres), where he proposed many hypotheses that revealed the universe’s structure...
The sum of all forces acting on a body is equal to the product of the mass of the body and the acceleration imparted by this sum of forces. It should also be noted that Newton’s second law is valid for bodies of constant mass, finite dimensions and moving forward....
Step 1 Scientists apply three traditional study designs, namely experiment, quasi-experiment, and non-experimental study. Random assignment and control groups are the distinctive framework elements and tools that distinguish the first category from the others. According to Rogers and Reverz (2019), it is a procedure in which “participants are randomly placed...
Introduction Statistics in any field are essential indicators of the dynamics of production processes. It solves many questions and complex problems in choosing a solution and mediating further tactics. For medicine, statistics are critical because they reduce error rates and expand the boundaries of employee control. With the help of...
Summary The hypothesis test study selected to help work on the conclusion is the Z-test. Z-test is a widely used hypothesis testing method that evaluates and determines whether or not an association or a finding is statistically significant (Dziak et al., 2020). A z-test examines the mean of a distribution...
Data Collection The purpose of the activity was to survey at least 20 individuals to find out the number of minutes (on average) that they drive one way to work. Social media platforms were used to collect the sample, from which I wrote out all the names of my contacts...
Introduction Research methods provide several solutions to obtain information, make inferences about factors underlying a particular phenomenon. However, compared to qualitative information that is based on individuals’ judgment and applied theories, quantitative information or statistical data draws information from factual figures that do not represent a researcher’s ideas. As a...
In order to test a complaint about the low weight of seeds in packages, the null hypothesis should be made that there is no significant deviation from the declared weight standard of 50 pounds. Accordingly, at the chosen significance level α = 0.05, a test will be carried out in...
Probability Theory In mathematics, probability theory is used as a vast field that studies the laws associated with random events. There are no unequivocal views as to when precisely the foundations of probability theory came into being. According to one version, it originated thousands of years ago when censuses were...
When asteroids and related outer-space objects crashed into Mars eons ago, they sent pieces of Mars’ core into space. These drifting rock pieces occasionally enter Earth’s atmosphere, where gravitational pull draws them inward (Siegel, 2018). Meteorites fall to Earth worldwide, but they are easier to locate in scorching or freezing...
The authors implemented a quantitative research design where the participants were taken into a psychology lab and given a questionnaire to fill out. The aim of the study was to find out whether immersion in social media sites has replaced strong religious commitment and spiritual serenity leading to low psychological...
Introduction The phenomenon of dangerous knowledge might seem like a self-contradictory one since knowledge is usually considered to be the source of global well-being and the promotion of progress. However, when representing a collection of facts on a singular issue and being applied as a means to unethical ends, without...
It is essential to note that exploring the topic of space exploration through the humanitarian lens can still use economic and technological factors. From a technological point of view, the classic satellite industry lags far behind SpaceX, which is steadily advancing capacity and decreasing the price of Falcon rockets, respectively....
Why is logistic regression needed? Predicting the likelihood of an event is useful when using logistic regression analysis. It aids in calculating the odds between any two classes. Logistic regression aims to find the most accurate model to explain the association between the dichotomous features of interest and a collection...
Type of Experiment Quasi-experimental design should be used in the study since the primary purpose of the experiment is to investigate the correlation between social-economic status and sentencing equality. Quasi and true experimental designs seek to determine the causal relationship between variables, but critical differences between the two reflect why...
The first step to using summary statistics is by understanding the type of data being dealt with. The fundamental difference between categorical and continuous level data is that quantitative variables prompt the question, how much? Whereas categorical variables prompt the question, what type? Hasted (2018) researched that quantitative variables can...
Introduction It is important to note that world hunger still remains to be one of the most critical problems on the global scale. Although humanity achieved massive progress in the development of advanced technology, which created an unprecedented level of prosperity and abundance, hunger still impacts the most vulnerable groups....
