Help the Stat Consulting Group by giving a gift. Cronbach's alpha is a measure of internal consistency, that is, how closely related a set of items are as a group. It is considered to be a measure of scale reliability. A high value for alpha does not imply that the measure is unidimensional.elp the Stat Consulting Group by giving a gift.

An endospore is an extremely resistant dormant cell structure produced by some bacterial species. If you break down the term endospore, 'endo-' means 'inside' and '-spore' refers to the 'dormant structure,' so the endospore is a structured formed inside the cell.
Endospores are formed by vegetative bacterial cells in a process called sporillation. Only one spore can be formed per bacterial cell, which can be formed in about eight hours and remain dormant for many years until the right environment triggers the cell to become active again. Some Bacteria make exospores or cysts instead of endospores but are not as resistant to harsh conditions. To watch step by step endospore formation please use following link: http://www.microbelibrary.org/images/Gauthier/Endopore_formation.htm. Endospores are green, vegetative (non endospore bacteria) cells are red.
