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...
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...
The ongoing COVID-19 pandemic became a challenge not only for humanity’s health but also for economies and businesses worldwide. The most significant challenge was imposed in small and medium enterprises (SME), requiring rapid adjustments and modifications in organizational structure to adapt to the situation (Klein & Todesco, 2021). Marketing research...
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...
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...
High-quality research is the foundation of informed decision making, judgment and problem-solving. The book “Why research methods matter: Essential skills for decision-makers” by Susan Gooden and Rajade Berry-James is an awakening to the public administrators of diverse rankings that they should have the competency to evaluate the quality and viability...
Introduction As established in contemporary research practice, qualitative and quantitative variants of research methodology are the leading paradigms that are used in answering topical questions. While the two methods can be mixed within a single study, they are independent, well-defined frameworks that inform data collection and analysis techniques used today....
Although stars appear to be eternal on the human time scale, they are born, live and die. Despite the fact that the life span of a star is extremely long, scientists have managed to analyze the evolution of celestial bodies and synthesize the knowledge gained. Thus, several stages of the...
In the article ‘Mapping Students’ Decision-Making Process across University Ranking Parameters: A Quantitative Study’, Sharma et al. (2020) implemented one-way ANOVA to indicate the difference between five parameters of the National Institutional Ranking framework. Analysis of variance or ANOVA is one of the most common statistical research methods that implement...
It is known that the universe is expanding at the present day, while its expansion rate is accelerating. As the universe consists of both dark energy and matter, they may have an influence on its expansion rate. There is a possible assumption that matter alone is enough for the universe...
Edison, who was born in Milan, Ohio, in 1847, did not obtain a formal education to the extent that most Americans did at the time. Early on, he experienced significant hearing loss, which served as the inspiration for several of his innovations. He started working as a telegraph operator at...
Introduction The use of statistical predictive models makes it possible to predict organizational changes, including sales. Although sales dynamics for companies are a difficult variable to accurately predict, underlying trends can be determined using simple linear regression equations. This paper uses regression analysis precisely to determine the effect of square...
One of the fundamental questions that every researcher should determine is to define their research interest. This point is above even the specific definition of a research topic since it represents the whole direction in which one will develop in the future. Since this choice can affect one’s entire career,...
In order to complete a robust, valid research project, it is vital to implement a fitting methodological vision that will reflect the study’s aims and objectives. Evidently, the contemporary practice of academic research possesses numerous tools that help to address profound topics with due levels of detail and credibility. At...
