RESEARCH BIAS
bias = unknown or unacknowledged error created during the design, measurement, sampling, procedure, or choice of problem studiedEXAMPLE #1: RQ: WHY DO BLACK STUDENTS SCORE LOWER ON IQ TESTS THAN WHITE STUDENTS?
EXAMPLE #2: RQ: "WHY DO SOME RAPE VICTIMS HAVE A HIGHER INCIDENCE OF CHILDHOOD INCEST THAN NON RAPE VICTIMS?"
EXAMPLE #3: WHAT EFFECT DO COMPANY PROVISION OF DAYCARE SERVICES HAVE ON THE JOB SATISFACTION OF WOMEN?
Just World Hypothesis = in a fair and just world, good things happen to good people and bad things happen to bad people
1. Assume homogeneity. Assume a minority or at-risk population is homogenous
2. Wonder about variation. Ask the basic question of research: "why dont they score the average?"
3. Speculate on a predictor of variation. Find some characteristic of the subgroup which may explain the deviance
4. Assume causality. If the characteristic is found in the minority subgroup, assume it explains the deviance from the norm
5. Attribution. Begin to view the characteristic as an attribute of the group
Sampling error leads to random error. Sampling bias leads to systematic error.
The thing that can be done to reduce bias is sampling random things
Standard error is random error, represented by a standard deviation. Sampling error is systematic error, represented by a bias in the mean.
bias
the hindsight bias
The scientific system of gathering data with bias and error in measurement are reduced in psychology.
Scientific method
Bias is systematic error. Random error is not.
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming
Sampling error leads to random error. Sampling bias leads to systematic error.
A systematic error occurring in a chemical measurement that is inherent in the method itself or caused by some artifact in the system, such as a temperature effect.
The thing that can be done to reduce bias is sampling random things
bias or primary
to make careful observations (got this off a study guide at school haha)
No, its not.
In stat the term bias is referred to a directional error in the estimator.
Alike:They are both an error that distort results in a particular way.Different: Emotional bias is distortion in cognition and decision making and expiremental bias is error that distorts results in a particular way.
