Security measures are important to protect confidential information, prevent unauthorized access, and reduce the risk of cyber attacks and data breaches. Implementing security measures helps to ensure the confidentiality, integrity, and availability of data and systems, which is crucial for maintaining trust with customers and stakeholders. Additionally, security measures can help organizations comply with regulations and standards related to data protection and privacy.
The dispersion of the data.
Because it measures the averages of a collection of data
If an access point receives data from a client station, it sends an acknowledgment to the client that the data has been received, this acknowledgment keeps the client from assuming that a collision occurred and prevent a data retransmission by the client.

Data collisions occur when data is transmitted on the same medium at the same time. Therefore, to avoid data collisions, connect all hosts to a full duplex switch.
Central tendency will only give you information on the location of the data. You also need dispersion to define the spread of the data. In addition, shape should also be part of the defining criteria of data. So, you need: location, spread & shape as best measures to define data.
The data type that measures the outcome of a study is quantitative data.
To increase productivity, communicate and collaborate data (including its changes), and to replicate data (preventing data loss). Data is not put into computers to increase security, as computers have the ability to easily leak data. You must take your own measures to prevent data leakage.
Actually there are several options and strategies in order to prevent data loss on a PC. One could for example store the personal / important data on a RAID 1 storage medium which actually mirrors the data. Another option would be to do regular backup stored on an external device of the most important data.
It can be used to restore data to the system in the event the data in the system are accidently lost or destroyed
