Data Collection by Survey

7.1K
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

Data collection is a systematic method of obtaining, observing, measuring, and analyzing accurate information. An experimental study is a standard method of data collection that involves the manipulation of the samples by applying some form of treatment prior to data collection. It refers to manipulating one variable to determine its changes on another variable. The sample subjected to treatment is known as “experimental units.”
An example of the experimental method is a public...

Key Elements for Plant Nutrition

21.8K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

The nursing history captures and records the patient's health status, so that a care plan evolves to meet the patient's individual needs. The nursing health history is a part of the initial assessment. A comprehensive history covers all health dimensions and plays a significant role in the assessment process. A comprehensive history includes the patient's biographical information, reasons for seeking health care, expectations, present and past health history, medications, and...

Area of Science:

  • Nutrition Science
  • Data Science
  • Public Health

Background:

  • The National School Lunch Program (NSLP) aims to provide nutritious meals to students.
  • Understanding the nutritional content of school meals is crucial for public health initiatives.
  • Collecting comprehensive school meal data can be challenging and time-consuming.

Purpose of the Study:

  • To explore the potential of web scraping for collecting school meal data.
  • To examine the variation in sodium content of popular entrees (pizza, chicken nuggets) within the NSLP.
  • To investigate the relationship between entree sodium content and school district characteristics.

Main Methods:

  • Utilized web scraping to collect daily school menu data from a national sample of school districts.
  • Linked web-scraped menu data with publicly available school district demographic and geographic information.
  • Analyzed sodium content variation in pizza and chicken nuggets across different school districts.

Main Results:

  • Web scraping proved to be a timely and cost-effective method for acquiring large-scale school meal data.
  • Significant variation in sodium content was observed for pizza and chicken nuggets served in the NSLP.
  • Sodium content differences were associated with geographic and socioeconomic characteristics of school districts.

Conclusions:

  • Web scraping is a viable tool for nutritional surveillance of school meal programs.
  • Findings can assist nutrition professionals in identifying areas for menu improvement and targeted interventions.
  • The approach has broader implications for monitoring and enhancing school nutrition policies.
