What is the important and most reliable measure of vulnerability?

The best way to asses vulnerability is to conduct qualitative study with a strong observational component. The life style of the people in the slums can tell the causes and effects of vulnerability. Focused group discussion and in-depth interviews helps.

Why is it important to assess vulnerabilities of various elements at risk?

Negative consequences of natural hazards are the result of both the frequency and intensity of the hazard and the vulnerability of the society or element at risk exposed. Therefore, vulnerability assessment is an essential step to reduce these consequences and consequently natural hazard risk.

How do you quantify vulnerability?

The quantification of vulnerability should include degree of exposure, and resilience or societal ability to recover from hazard impacts without compromising long-term prospects. It is important to identify the factors or conditions that generate, increase and builds up vulnerability (Maskrey 2011).

What is the best measure of reliability?

In general, a test-retest correlation of +. 80 or greater is considered to indicate good reliability. Again, high test-retest correlations make sense when the construct being measured is assumed to be consistent over time, which is the case for intelligence, self-esteem, and the Big Five personality dimensions.

What is the most reliable measure?

The mean is the most frequently used measure of central tendency because it uses all values in the data set to give you an average. For data from skewed distributions, the median is better than the mean because it isn’t influenced by extremely large values.

What is the most important part of a risk assessment?

decide how likely it is that someone could be harmed and how seriously (the risk) take action to eliminate the hazard, or if this isn’t possible, control the risk.

What are the most important attributes in evaluating risks?

Effectively applied using business strategy as a context, risk assessment considers such attributes as impact, likelihood, velocity and persistence. Like any other worthwhile business activity, risk management requires a process with a clear purpose, reliable inputs, well-designed activities and value-added outputs.

Can vulnerability be measured?

Prevalent Vulnerability Index (PVI) that measures three tangible social-related vulnerability aspects: hazard exposure and physical susceptibility, socioeconomic fragility, and resilience. Risk Management Index (RMI) that measures institutional and community performance on disaster risk management.

What are the most important methods to quantify risk?

Single-point probability analysis An expected value can be calculated for each significant risk by multiplying the likelihood of the risk occurring (probability) by the size of the consequence. This risk premium is expressed in monetary terms and provides an estimate of the cost of accepting all the risk.
