When collecting and summarizing data, the methods used for data collection can significantly affect the reliability and validity of the data.
* Descriptive Statistics:
* Concerned with summarizing data but not the method of collection.
* Data Accuracy:
* Ensured through proper collection methods but is an outcome rather than an influencing element.
* Measurement Scales:
* Refers to the types of data (nominal, ordinal, interval, ratio) but not directly affected by redundancy, versatility, and flexibility.
* Data Collection Methods:
* The techniques and processes used to gather data.
* Ensuring redundancy, versatility, and flexibility in data collection methods can help in obtaining comprehensive and accurate data.
