go into depth on how it occurs and the best ways to avoid it. So, without further to do, let’s get started! What is Researcher Bias? Researcher bias is a form of response coverage error bias that occurs whenever there is a flaw in a survey’s research design. This systematic error can be caused by problems with various different aspects of a study’s research methodology. Most of these issues arise from lack of planning out a clear research purpose and objectives as well as the absence of secondary research before initiating a study. A lack of planning and overall understanding of the tabulation of collected data topic being studied can make it difficult to create a survey with the correct list of questions and lead to higher amounts of error. Combatting Researcher Bias The following is a list of the common types of researcher bias and some tips on how to avoid each. This list has been altered from the previous schools of thought to pertain to only online research projects: 1. Surrogate Information Error: This form of researcher bias is created by a variation in the information needed to address the marketing problem and the information the researcher is collecting. This problem can occur in various ways, but most often is due to a lack of understanding by the researcher. For example, let’s say the research purpose of a survey was to figure out what type of ice cream is the favourite in a sample. The researcher asks, “Do you like chocolate, vanilla, or strawberry ice cream the best?” Though there are many other types of ice cream, they did not come to the researchers mind. Now instead of measuring the most popular ice cream, the study measures the preference between these three types of ice cream. The best way to avoid

Bias can occur in the planning, data collection, analysis, and publication phases of research. Understanding research bias allows readers to critically and independently review the scientific literature and avoid treatments which are suboptimal or potentially harmful. A thorough understanding of bias and how it affects study results is essential for the practice of evidence-based medicine.The British Medical Journal recently called evidence-based medicine (EBM) one of the fifteen most important m
Minimize Errors And Create More Usable Websites: Part I Errors happen. It's inevitable that any system will fail at times. Often failures are attributed to human error. Most, though http://vanseodesign.com/web-design/minimize-errors-part-i/ are really due to design errors. As designers what can we do to minimize errors and their effects on our sites and in our applications? Fortunately we can communicate through a variety design strategies in a way that reduce both the frequency of errors on the sites we build and the magnitude of those errors that inevitably occur. There are a number of strategies and a lot to cover. We'll begin today with how to a look at errors in general, the different types and causes of errors, and offer a quick mention of the strategies at our disposal. Then we'll look in more detail at the first of these strategies for countering errors, affordance. The 2 Types of Errors Errors are actions taken or not taken that lead to unintended results. There are two main types of errors that can occur, slips and mistakes, each with design error in their own subtypes of errors. Slips Slips are errors of action or errors of execution. An example I'm sure you're familiar with is when you find yourself driving to a common destination when you meant to drive somewhere else. Another example is when you're adding a series of numbers in a column and the phone rings and you temporarily lose your place and skip a number before continuing to add again. Slips occur when the action taken was not the one intended and they're usually the result of the unconscious. They frequently result from a change in the usual routine or the interruption of an action you were taking. There are two types of slips. Action slips result from changes to repetitive tasks. The driving example above is an action slip (PDF), since the error comes from varying the routine. We help prevent action slips by providing clear and distinctive feedback and through the use of confirmations, constraints, affordance, and mappings (all to be covered later in this post or parts ii or iii). Sticking to conventions can also help prevent action slips as they maintain the status quo. Attention slips result from distractions and interruptions. The number adding example is an attention slip since the slip occurs due to an interruption of your current act
