Determination of Expected Frequency01:08

Determination of Expected Frequency

2.6K
Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...

Expected Value

The expected value is known as the "long-term" average or mean. This means that over the long term of experimenting over and over, you would expect this average. The expected average is represented by the symbol μ. It is calculated as follows:

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Central to the success of community-based interventions is the...

Line Loss01:10

Line Loss

545
The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

Weighted Mean00:57

Weighted Mean

6.4K
While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

Summary
This summary is machine-generated.

Many people have unrealistic weight loss goals, especially women and those with obesity. Personalized care is needed to help patients set achievable weight loss targets and improve quality of life.

Area of Science:

  • Obesity Research
  • Behavioral Science

Background:

  • Weight loss expectations are typically studied in clinical populations.
  • This study examines weight loss expectations in a large, non-clinical population.

Purpose of the Study:

  • To explore patient weight loss expectations in a general population.
  • To identify determinants of unrealistic weight loss goals (≥10% initial weight).

Main Methods:

  • Community-based survey of 3916 Belgian adults.
  • Assessed "dream", "goal", "happy", "acceptable", and "disappointed" weights.
  • Measured body mass index (BMI), body image discrepancy (BID), subjective norm (SN), quality of life (QoL), and other factors.

Main Results:

  • Median weight loss targets ranged from 5kg ("disappointed") to 21kg ("dreamed").
  • Recommended weight loss targets (5-10%) were considered disappointing.
  • Unrealistic goals were linked to female gender, weight loss activity, overweight history, and lower QoL in overweight/moderately obese individuals.
  • Severe and morbid obesity categories showed high risk for unrealistic goals.

Conclusions:

  • Urgent need to manage patient expectations towards more modest weight loss outcomes.
  • Personalized care is essential, considering individual profiles, expectations, and determinants of weight loss goals.
