1. Name and describe one data collection instrument that is used in YOUR field. It does not have to be your current field.
* this discussion is about the observer's reliability when using the instrument....NOT the instrument's reliability...see below.
2. How do you, OR would you, assure interobserver reliability when using this instrument? Please describe thoroughly.
3. How do you, OR would you, assure intraobserver reliability when using this instrument? Please describe thoroughly.
4. Respond to at least one of your peers' posts.
Note: In spite of the fact that you are selecting a data collection INSTRUMENT for this posting.....this concept is about the OBSERVER'S reliability when using this instrument.
For example, as the observer, a Weight Watcher meeting leader might use a data collection instrument such as a digital scale. With that in mind, to answer this forum, the observer would indicate how he/she practices interobserver reliability with all of the other WW meeting leaders at one location: they all use the same scale, they all allow shoes to come off and pockets to be emptied; they all weigh at the beginning of the meeting.....etc. In other words, the leaders calibrate how they "observe" the data they are collecting with the data collection instrument.
In contrast, if the observer is the only person that is overseeing the data collection at a meeting, he/she may describe intrarelibility as their standard routine of data collection (each and every time) - having everyone stand on the same place on the scale, having everyone empty their pockets, weighing everyone at the beginning of the meeting. So, to assure that the observer has intraobserver reliability, he/she standardizes their own methods and to make certain to follow the same methods with everyone that is observed.
This course is about recognizing and using evidence. So, in order to earn full points, you will need to support each of your postings with the appropriate evidence.
One of the data collection instrument is Surveying.
Surveying which is generally used to collect data and information from people . It can be used both in qualitative and quantitative research. In case of census data , survey method is used. Qualitative type of research involves open ended questions whereas in case of quantitative oriented research , the questions are close ended ones.
Interobserver reliability is the estimate of consistency .It is mostly used in interviews . Conducting survey on census data is something where the interview is taken in a large sample of population. Majorly the opinion of people hardly differs from year to year. The consistency is more or less same . Eg : What is the percentage of people smoking in our country? Out of it , what is the percent of Females having cigarettes?
In this case , it will predict the consistency of people having cigarettes .
