What is an Experiment?

17.4K
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

6.6K
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

16.1K
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

8.9K
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 Experiments01:16

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.

Area of Science:

  • Oncology
  • Neurosurgery
  • Otolaryngology

Background:

  • Temporal bone chondrosarcoma (TBC) is a rare primary malignancy of the temporal bone.
  • Limited clinical experience exists regarding TBC diagnosis and treatment.
  • Optimal management strategies for TBC remain debated.

Purpose of the Study:

  • To summarize the diagnostic and treatment experience of TBC.
  • To provide insights for improving the quality of life for future TBC patients.

Main Methods:

  • Retrospective analysis of 10 TBC patients treated between June 2009 and June 2018.
  • Data collected on patient demographics, symptoms, tumor origin, and treatment outcomes.

Main Results:

  • Facial paresis (50%) and hearing loss (40%) were the most frequent presenting symptoms.
  • Tumors predominantly originated in the middle ear mastoid area (80% involving the jugular foramen).
  • All patients achieved disease-free survival at a median follow-up of 28.8 months.

Conclusions:

  • TBC frequently arises in the middle ear mastoid region and can extend to the jugular foramen.
  • Individualized surgical approaches focusing on complete tumor removal with minimal neurovascular damage are effective.
  • This strategy ensures long-term cancer control and low morbidity.
