Ordinal Level of Measurement00:55

Ordinal Level of Measurement

33.5K
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
Data measured using an ordinal scale are similar to nominal scale data, but there is one major difference. The ordinal scale data can be ordered. An example of ordinal scale data is a list of the top five national parks...

Analysis Methods of Pharmacokinetic Data: Model and Model-Independent Approaches

530
Drug disposition in the body is a complex process and can be studied using two major approaches: the model and the model-independent approaches.
The model approach uses mathematical models to describe changes in drug concentration over time. Pharmacokinetic models help characterize drug behavior in patients, predict drug concentration in the body fluids, calculate optimum dosage regimens, and evaluate the risk of toxicity. However, ensuring that the model fits the experimental data accurately...

Modeling with Differential Equations

Population dynamics can be described mathematically by considering the population size P(t) as a function of time. The rate of change of the population is then represented by the derivative of P(t). A simple assumption is that the rate of growth is proportional to the size of the population itself. This leads to an exponential growth model, where the population increases rapidly without bound. While this is a useful first approximation, it does not reflect realistic long-term...

Chemical Equations

81.3K
Chemical equations represent the identities and relative quantities of substances involved in a chemical reaction. The substances undergoing reaction are called reactants, and their formulas are placed on the left side of the equation. The substances generated by the reaction are called products, and their formulas are placed on the right side of the equation. Plus signs (+) separate individual reactant and product formulas, and an arrow (→) separates the reactant and product (left and right)...

Nonstandard Reaction Conditions
The interconnection between standard cell potentials and various thermodynamic parameters such as the standard free energy change ΔG° and equilibrium constant K has been previously explored. For example, a redox reaction involving zinc(II) and tin(II) ions at 1 M concentration with Eºcell = +0.291 V and ΔG° = −56.2 kJ is spontaneous.

Thermochemical Equations

For a chemical reaction (the system) carried out at constant pressure – with the only work done caused by expansion or contraction – the enthalpy of reaction (also called the heat of reaction, ΔHrxn) is equal to the heat exchanged with the surroundings (qp).

Area of Science:

  • Statistics
  • Psychometrics
  • Quantitative Psychology

Background:

  • Missing data are prevalent in studies employing structural equation modeling (SEM).
  • Existing methods for addressing missing ordinal data lack systematic evaluation within SEM contexts.
  • This gap hinders robust statistical analysis and reliable model interpretation.

Purpose of the Study:

  • To systematically evaluate and compare five distinct methods for handling missing ordinal data in SEM.
  • To identify the most effective methods based on performance under various missing data conditions.
  • To provide evidence-based recommendations for researchers using SEM.

Main Methods:

  • Utilized Monte Carlo simulation to generate data with varying missingness patterns.
  • Compared one direct robust estimation method against four multiple imputation techniques.
  • Assessed method performance based on accuracy, bias, and efficiency in SEM parameter estimation.

Main Results:

  • Simulation results indicated significant differences in the performance of the evaluated methods.
  • Multiple imputation methods generally outperformed the direct robust estimation method under most conditions.
  • Specific imputation strategies demonstrated superior accuracy and stability for SEM analyses.

Conclusions:

  • Researchers should carefully select methods for handling missing ordinal data in SEM.
  • Multiple imputation is often a preferred strategy, but the choice of imputation method matters.
  • The study provides practical guidance to improve the quality and validity of SEM research with missing ordinal data.
