In case field studies are less than required, the chance of the findings being wrong is...

Aspects of Statistical Estimation

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...

In the Eye of a Supernova: An Interview with an Expert

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)....

Statistical Significance and Meaningfulness

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,...

Anthropocene and Human Impact on the Earth System

Summary Today, humanity’s effect on the planet’s ecosystems is so pervasive and dynamic that it may be compared to the power of some of nature’s most formidable forces. However, the term Anthropocene, which was established around a decade ago, has only lately been widely, though informally, used in the global...

Linear Regression in Health Sector

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...

Copernicus’ Statement in “De Revolutionibus”

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...

Newton’s Second Law Applied to Air Glider

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....

Study Designs, Their Benefits and Limitations

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...

Utilization of Statistical Data

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...

Hypothesis Test Study Description

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...

Marketing research...

Probability Theory in Mathematics

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...

Martian Meteorites That Have Landed on Earth

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...

Space Exploration Through the Humanitarian Lens

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....

Logistic Regression, Its Purpose and Calculations

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...

Socioeconomic Status and Sentencing Severity Experiment

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...

Analysis of variance or ANOVA is one of the most common statistical research methods that implement...

Positionality and Perspective in Qualitative Research

Introduction and Definition Research processes require sharing of spaces between the researcher and participants. A researcher may take a stance on a particular subject by forming biases and perceptions of others and how outsiders perceive them. Participants may have a specific belief that contradicts the ontology and epistemology of the...

Dark Energy and Its Significance for the Universe

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...

Determining the Polynomial Model for Amazon

Introduction The polynomial model is an integral concept in mathematics, especially in determining relationships. It is a form of regression where the relationship between dependent and independent variables is determined (Fox & Burks, 2019). For example, the model can identify the relationship between Amazon’s net income/loss and sales. However, there...

Internal and External Validity in Quantitative Research

Summary Internal and external validity are significant factors in quantitative research and should always be considered before and during the experiment. The former is the level of control of the independent variable on the outcomes of the dependent variable (Cox, 2020). It implies that internal validity is responsible for the...

Data Analysis in Hypothesis Testing
