What is one factor that will be different between the experimental group and the control group?

The experimental group will receive the treatment or intervention being studied, while the control group will not receive the treatment and instead may receive a placebo or standard care. This difference in treatment exposure is a key factor that distinguishes the two groups in an experiment.


What is the difference between positive and negative control in an experiment?

In an experiment, a positive control is used to show that the experiment can detect a specific response, while a negative control is used to show that the experiment does not detect a response when it should not.


What is one factor that will be different between the experimental group in the control group?

The experimental group receives the treatment or intervention being studied, while the control group does not receive the treatment and is used for comparison. This is the primary difference between the two groups in an experiment.


To minimize the extent to which outcome differences between experimental and control groups can be attributed to placebo effects researchers make use of?

random assignment of participants to groups, blinding both participants and researchers to group assignment, and including a control group that receives a placebo treatment or standard care.


Difference between reference standard and working standard in analytical lab?

A reference standard is the traceable, raw material standard (usually in crystallized form) that you dissolve and volumetrically dilute to make your working standard. The working standard is what you use to "do your work." Let's say you are performing an HPLC purity and degradation assay on aspirin tablets for your client. The client corporation would supply the reference standard(s) (or in this case could be purchased from the US Pharmacopeia) with a lot number, purity coefficient and expiration date (among other things like storage requirements). This information makes it traceable and is recorded in the preparation notebook. Then per the assay method the working standard is dissolved in a volumetric flask and diluted to volume (with subsequent dilutions if necessary) to make the working standard. The working standard is then used to make calibration curve injections on the HPLC to estimate the quantities of your aspirin tablets being analyzed. Note: In the above example, reference standards are also used to make a system suitability solution. This would contain the A) reference standard material used for the calibration curve and B) another reference standard of at least one possible degradant to show peak separation.

What is Sand bath temperature calibrator?

A sand bath temperature calibrator is a high precision temperature controlled fluidized sand bath instrument designed to analyze the performance of other temperature control or temperature indicating instruments. Due to its high precision it can be used as a standard for calibrating other temperature control or indicating instruments.

What is the difference between variable constant and control?

A constant is always fixed and won't change in an experiment. The control is the standard that you are testing against to see how experiment outcomes change when the testing factors are altered.
