Data Collection by Experiments01:13

Data Collection by Experiments

27.9K
Data collection is a systematic method of obtaining, observing, measuring, and analyzing accurate information. An experimental study is a standard method of data collection that involves the manipulation of the samples by applying some form of treatment prior to data collection. It refers to manipulating one variable to determine its changes on another variable. The sample subjected to treatment is known as “experimental units.”
An example of the experimental method is a public...

Randomized Experiments

9.2K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

What is an Experiment?

19.6K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Crossover Experiments

4.7K
Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

Experimental Designs

18.4K
An experimental design is a systematic process that allows researchers to evaluate the relationship between dependent and independent variables. There are three widely used types of experimental design - pre-experimental design, true experimental design, and quasi-experimental design. In pre-experimental design, the researcher compares the data before and after some interventions or treatments. The true-experimental design has more than one purposefully created group, a commonly measured...

Controls in Experiments01:13

Controls in Experiments

18.7K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Area of Science:

  • Behavioral science
  • Computer science
  • Human-computer interaction

Background:

  • Conducting synchronous experiments online and in the lab can be challenging.
  • Existing frameworks may not adequately support large group sizes, real-time data collection, or simultaneous experiments.

Purpose of the Study:

  • Introduce nodeGame, a free, open-source JavaScript/HTML5 framework.
  • To provide a flexible platform for behavioral research with specific support for larger groups, real-time experiments, and simultaneous experiment batches.

Main Methods:

  • nodeGame utilizes a modular source code and an application programming interface (API).
  • Experimenters can create new strategic environments and configure the platform via the API.
  • The framework is designed for zero-installation and runs directly in the browser window.

Main Results:

  • nodeGame supports larger group sizes for online and lab-based experiments.
  • It facilitates real-time and discrete-time experimental designs.
  • The framework enables batches of simultaneous experiments.

Conclusions:

  • nodeGame offers a versatile and accessible solution for modern behavioral research.
  • Its cross-device compatibility (desktops, laptops, smartphones, tablets) enhances accessibility.
  • Version 3.0 is available with extensive documentation online.
