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.
Since they're commonly called spores, some people think that bacterial endospores are associated with bacterial reproduction. Really, creation of an endospore is a survival mechanism used by bacteria to withstand harsh environmental conditions. Bacteria propagate when times are good. When times are bad, certain bacteria have the capability to shrink down and encrust critical cellular elements in a tough casing.
