Steps in Outbreak Investigation01:18

Steps in Outbreak Investigation

171
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Statistical Methods for Analyzing Epidemiological Data01:25

Statistical Methods for Analyzing Epidemiological Data

484
Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:

Pareto Chart00:52

Pareto Chart

6.9K
A Pareto chart is a bar graph or a combination of both line and bar graphs. The bar lengths represent the individual values or the frequency, while the lines represent the cumulative total values. In this chart, the longest bars are arranged on the left and the shortest bars on the right, which makes it easier to read and interpret the data. It can also be called a Pareto diagram or Pareto analysis.
The Pareto chart is named after the Italian economist Vilfredo Pareto, who described the Pareto...

Issues And Trends In Healthcare Delivery System

5.8K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.

Pie Chart01:04

Pie Chart

14.3K
A pie chart (or a pie graph) is a circular graphical chart or a pictorial representation of categorical data. It is divided into slices of pie each indicating numerical proportions. It is also used to show the relative sizes of data in a single chart.
In a pie chart, the central angle, the arc length of each slice, and the area are directly proportional to the quantity or percentage it represents. Some real-world examples that can be depicted using pie charts include marks obtained by students...

Correlation01:09

Correlation

12.4K
In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

Area of Science:

  • Consumer Behavior
  • Digital Marketing
  • Big Data Analytics

Background:

  • The COVID-19 pandemic profoundly impacted consumer habits and the food delivery industry.
  • Understanding shifts in consumer perception is crucial for businesses operating in the food delivery sector.

Purpose of the Study:

  • To analyze changes in consumer perceptions of food delivery services before and after the COVID-19 pandemic.
  • To identify key terms and sentiment trends associated with food delivery using social media big data.

Main Methods:

  • Utilized text mining, Concor analysis, and sentiment analysis on social media data.
  • Compared keyword associations and sentiment networks for food delivery in 2019 versus 2021.
  • Extracted and analyzed positive and negative emotional keywords related to food delivery searches.

Main Results:

  • Prominent keywords shifted from 'dining-out' and 'delicious' (2019) to 'COVID-19' and 'application' (2021).
  • Sentiment analysis showed a 2.85% decrease in positive keywords and a corresponding increase in negative keywords.
  • Positive emotions like 'joy' and 'interest' declined, while negative emotions such as 'sadness' and 'fear' increased post-pandemic.

Conclusions:

  • The COVID-19 pandemic negatively altered consumer sentiment towards food delivery.
  • There was a notable decrease in positive emotional expressions and an increase in negative ones concerning food delivery services.
  • The findings highlight the need for the food delivery industry to address evolving consumer needs and emotional responses.
