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 priarily by gram + rods in response to harsh environmental conditions. They allow long-term survival of the bacterium.In addition to protection from heat and chemicals, endospores prevent dessication of the cell and are able to survive harsh conditions for weeks, months or even years. This allows survival of the bacteria in conditions such as dry soil.
