Design Example: Analyzing Capacity Contours for Flood Risk Assessment01:17

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

36
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Time-Series Graph00:54

Time-Series Graph

4.3K
A time-series graph is a line graph with repeated measurements taken at successive intervals of time. It is also called a time series chart. To construct a time-series graph, one must look at both pieces of a paired data set. The horizontal axis is used to plot the time increments, and the vertical axis is used to plot the values of the variable that one is measuring. By using the axes in this way, each point on the graph will correspond to time and a measured quantity. The points on the graph...

Survival Curves01:18

Survival Curves

88
Survival curves are graphical representations that depict the survival experience of a population over time, offering an intuitive way to track the proportion of individuals who remain event-free at each time point. These curves are widely used in fields such as medicine, public health, and reliability engineering to visualize and compare survival probabilities across different groups or conditions.
The Kaplan-Meier estimator is the most common method for constructing survival curves. This...

Uncertainty: Overview00:59

Uncertainty: Overview

498
In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.

Probability Histograms01:17

Probability Histograms

11.0K
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.

Relative Risk01:12

Relative Risk

107
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Area of Science:

  • Data visualization
  • Risk communication
  • Scientific communication

Background:

  • Surprising data visualizations can erode trust and lead to poor risk decisions, especially when prior knowledge is limited, as seen during the COVID-19 pandemic.
  • Effective risk communication is crucial for public health and safety, particularly for novel threats.

Purpose of the Study:

  • To explore the efficacy of narrative visualizations in balancing the benefits of static visualizations, interactive simulations, and anecdotes.
  • To determine if narrative visualizations can mitigate reduced concern caused by static visualizations in risk communication.
  • To investigate the mechanisms by which narrative visualizations enhance risk perception and data trust.

Main Methods:

  • Empirical studies comparing narrative visualizations with static visualizations for communicating COVID-19 transmission risk.
  • Mediation analysis to assess the impact of perceived understanding and data trust on risk concern.

Main Results:

  • Viewing narrative visualizations mitigated the reduced concern induced by static visualizations for COVID-19 transmission risk (Study 1).
  • Narrative visualizations were more effective than static visualizations in increasing concern about large risks by enhancing perceived understanding and trust in data (Study 2).

Conclusions:

  • Narrative visualizations represent a distinct and powerful class of tools for scientific communication.
  • These visualizations are particularly valuable in contexts with surprising data and where empirical understanding is paramount.
  • Narrative visualizations can improve public engagement with and trust in scientific data, leading to more informed risk assessment.
