Secondary data refers to data that is collected by someone other than the primary user. Secondary data analysis can save time that would otherwise be spent collecting data and, particularly in the case of quantitative data , can provide larger and higher-quality databases that would be unfeasible for any individual researcher to collect on their own. However, secondary data analysis can be less useful in marketing research, as data may be outdated or inaccurate. Government departments and agencies routinely collect information when registering people or carrying out transactions, or for record keeping — usually when delivering a service. This information is called administrative data.

Халохот стиснул револьвер в руке, не вынимая из кармана. Он будет стрелять с бедра, направляя дуло вверх, в спину Беккера. Пуля пробьет либо позвоночник, либо легкие, а затем сердце.
