Nominal Level of Measurement00:56

Nominal Level of Measurement

33.6K
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. Not every statistical operation can be used with every set of data. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
The data that cannot be measured but can be grouped into categories fall under the nominal level of measurement. Data that is measured using a nominal...

Taste Buds and Receptors01:20

Taste Buds and Receptors

3.4K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Data Reporting and Recording

5.1K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

SBAR II: Application of SBAR

5.3K
SBAR is an effective communication tool used by healthcare professionals to communicate patient information accurately. SBAR stands for Situation, Background, Assessment, and Recommendation. For a better understanding, an example is given below.
SBAR Report from a Nurse to a Health Care Provider
S: "Hello, Dr. Smith. This is Jane, RN, from the Med Surg unit. I am calling to tell you about Ms. White in Room 210, who is experiencing increased pain and redness at her incision site. Her recent...

Encoding01:19

Encoding

544
Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing.
Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

Bar Graph01:07

Bar Graph

20.5K
A bar graph is also called a bar chart and consists of bars that are separated from each other. It either uses horizontal or vertical bars to show comparisons among categories. The bars can be rectangles, or they can be rectangular boxes (used in three-dimensional plots). One axis of the graph represents the specific categories being compared, and the other axis shows a discrete value. In this graph, the length of the bar for each category is proportional to the number or percent of individuals...

Area of Science:

  • Nutrition Science
  • Public Health Research
  • Environmental Health

Background:

  • Assessing the youth food environment is crucial for understanding dietary patterns.
  • Existing methods for evaluating food environments may lack standardization.
  • Reliable data collection tools are needed to accurately code restaurant offerings.

Purpose of the Study:

  • To create a dependable electronic tool for coding restaurants within the youth food environment.
  • To ensure the tool is informed by expert knowledge and academic literature.
  • To validate the tool's reliability across different users.

Main Methods:

  • Registered Dietitians were surveyed to identify key health-centric food environment features.
  • An academic literature review informed the selection of features for the data collection tool.
  • Inter-rater reliability was assessed using coders with varying nutrition expertise near three high schools.

Main Results:

  • Sixteen distinct restaurant food environment codes were developed.
  • The data collection tool achieved a mean inter-rater reliability of 90.7% agreement.
  • High reliability was observed across coders regardless of their nutrition training background.

Conclusions:

  • The developed tool provides a reliable method for collecting data on local restaurant food environments.
  • Academic and public health professionals can utilize this tool for informed research and interventions.
  • This tool supports consistent assessment of food environments impacting youth.
