What is an Experiment?01:12

What is an Experiment?

19.0K
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...

Thomson's e/m Experiment

6.9K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Controls in Experiments

18.2K
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...

Randomized Experiments

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.

Crossover Experiments

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.

Summary
This summary is machine-generated.

Shiftwork preferences change with experience. Early and late-career shiftworkers dislike night shifts, while mid-career workers prefer flexible hours, unlike controls who favor societal norms.

Area of Science:

  • Occupational Health
  • Chronobiology
  • Sociology of Work

Background:

  • Shiftwork is common but often leads to dissatisfaction, which can increase with age and experience.
  • Understanding preferred work hours is crucial for improving shiftworker well-being and work-life balance.

Purpose of the Study:

  • To investigate how preferred paid work times differ between shiftworkers with varying lengths of experience and age-matched non-shiftworkers.
  • To explore the evolution of time perception and work hour preferences across a career in shiftwork.

Main Methods:

  • A questionnaire assessed the perceived value of each hour across the week (0-10 scale) for shiftworkers and controls.
  • Data were analyzed using mean and standard deviation matrices, with unpaired t-tests identifying significant group differences.
  • Participants were categorized by shiftwork experience (0-5 years, 17-30 years, 30+ years) and compared to controls.

Main Results:

  • Preferred work hours significantly change with years of shiftwork experience.
  • Shiftworkers in their first 5 years and those with over 30 years experience showed low preference for night work.
  • Shiftworkers with 17-30 years experience exhibited a preference for working at any time, extending preferences to evenings and weekends, unlike controls who adhered to societal norms.

Conclusions:

  • Initial shiftwork may attract individuals with flexible time perceptions, but these perceptions can shift over a career.
  • Shiftwork experience alters an individual's valuation of time and preferred work scheduling.
  • Findings suggest a need for adaptable work scheduling strategies that consider the evolving preferences of shiftworkers.
