Random sampling does not eliminate any extraneous variable, it only ensures it is equal between all groups. Understanding nursing research. Some of the variables cannot be helped. The first category involves the creation of groups by random assignment.
The amount of influence that extraneous variables can have on dependent variables is through control (Grove & Burns, 2011). For example, Kupinski et al. 1-According to Grove & Burns, extraneous variables “exist in all studies and can interfere with obtaining a clear understanding of the relationships among the study variables” (2011). Others can be controlled for by careful consideration and control mechanisms implemented within the study. Controlling for this could mean working with a specific age group of people, or engaging in an all male or all female study so that the extraneous variables do not affect the results of the research. A second type of nesting is a nesting structure within the treatment factors being examined. © 2020 BrilliantNursingPapers.com All rights reserved.Methods to Control Extraneous Variables In Nursing Assignment. An alternative way of eliminating confounding due to The hallmark of this type of study is the random assignment of participants to different treatments. These methods fall into two categories. When extraneous variables present itself, it can prevent researchers from developing a clear picture of the cause and effect or the ways that each study variables interact with one another. Learn. In order to avoid the confounding of a known Unknown extraneous variables can be controlled by randomization. Randomization is when treatments are randomly given to the experimental groups.
participants to conditions can control a variety of extraneous variables.
8th PPT (Design Strategies For Controlling Extraneous Variables) STUDY. Created by. An alternative way of eliminating confounding due to extraneous variables is to include only those individuals at a specific level of the confounding variable. In order to remove biases associated with different scaled feature values and to preserve good numerical behavior, all of the features should be first normalized using the entire database (samples in all classes) withAfter normalization, the mean and standard deviation of every feature are equal to zero and one, respectively. Then the variance of (3 is given by, say, V (3) = EZwj, V(1i -x23) = E wj Vj.

In general, the good features used in a machine learning classifier should possess the following characteristics:Large interclass mean distance (discrimination): Features in different classes should have significantly different values.Small intraclass variance (reliability): Features should have similar values for objects of the same class.Low correlation with other features (independence): Features should not be strongly correlated to each other.If the number of initially selected features is limited, direct measurement of feature characteristics can be a choice to search for effective features and eliminate redundant ones.
