Resumen
La gente interpreta las visualizaciones de datos usando sesgos como "la oscuridad es más". Este estudio muestra que el sesgo "opaco-es-más" puede activarse sin cambios significativos en la ligereza, y revela un nuevo sesgo "saturado-es-más".
Área de la Ciencia:
- Psicología Cognitiva Psicología cognitiva.
- Información Visualización de la información
- Interacción hombre-computadora Interacción hombre-computadora.
Sus antecedentes:
- Las personas confían en los sesgos de mapeo de cantidad-color (por ejemplo, oscuro-es-más, opaco-es-más) para la interpretación de datos.
- Investigaciones anteriores sobre el sesgo opaco-es-más confundían la opacidad con variaciones de luminosidad.
- Las condiciones perceptivas para activar estos sesgos siguen sin estar claras.
Objetivo del estudio:
- Para investigar si el sesgo opaco-es-más puede ser activado sin variación sustancial de la luminosidad.
- Para explorar el papel de la saturación del color en la percepción de la cantidad dentro de las visualizaciones de datos.
- Para identificar nuevos sesgos que influyen en las asignaciones de color y cantidad.
Principales métodos:
- Manipulación de la saturación del color para variar la opacidad percibida, mientras se controla el contraste de luminosidad (L* en CIELAB).
- Presentó a los participantes visualizaciones y evaluó sus interpretaciones de la cantidad en función de las propiedades del color.
- Se analizaron las respuestas para determinar la influencia de la saturación y la opacidad en la magnitud percibida.
Principales resultados:
- El sesgo opaco-es-más se activó incluso con una mínima variación de la luminosidad.
- La evidencia surgió para un nuevo sesgo "saturado-es-más", donde una mayor saturación implica una mayor magnitud.
- La saturación del color influye de forma independiente en la cantidad percibida, distinta de la ligereza.
Conclusiones:
- El sesgo opaco-es-más no depende únicamente de una variación sustancial de la luminosidad.
- La saturación del color es una característica visual clave que puede impulsar inferencias de magnitud y cantidad.
- Los hallazgos informan el diseño de visualizaciones de datos más efectivas e intuitivas mediante el aprovechamiento de las propiedades del color.

Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

01:05Histogram
18.4K
The histogram is a graphical representation in the x-y form of data distribution in a data set. The horizontal x-axis is labeled with what the data represents (for instance, distance from your home to school). The vertical y-axis is labeled either frequency or relative frequency (or percent frequency or probability).
A histogram graph consists of contiguous (adjoining) boxes. The heights of the bars correspond to frequency values. The graph will have the same shape with respective labels. The...

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

01:06Skewness
19.9K
The measures of central tendency calculated from a data set may not reveal much about its intrinsic distribution. If a plot is made of the data set’s values, the mean and the median may not only differ, but also the plot may have more values on one side of the central tendencies. Such a data set is said to be skewed towards that side.
The longer the tail of the plot on one side, the more skewed it is. The skewness of a data set’s values suggests that the measures of central tendency...

1.6K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

01:17Probability Histograms
13.3K
A probability histogram is a visual representation of a probability distribution. Similar a typical histogram, the probability histogram consists of contiguous (adjoining) boxes. It has both a horizontal axis and a vertical axis. The horizontal axis is labeled with what the data represents. The vertical axis is labeled with probability. Each rectangular bar in the histogram is 1 unit wide, which suggests that the area under each bar equals the probability, P(x), where x is 1, 2, 3, and so on.
