Answer:
Pathological aging
Explanation:
Pathological aging is usually associated with older adults; it is a form of aging that is characterized by severe long term and short term memory loss. A feature of pathological aging is the increase in cerebrovascular and neurodegenerative disorders. Another feature of pathological aging is synaptic and neuronal loss. Individuals begin to forget things that they originally do not forget, like forgetting their driving routes.
Answer:Cronbach's alpha
Explanation:
Cronbach's alpha is used to measure consistency interms of how closely associated items in a group are.
It measures the scale of reliability as a coefficient of reliability not statistically.
below is a formula that is used to calculate this reliability.
α=N¯c/¯v+(N−1)¯c
Here N equate to the number of items, ¯c is the average inter-item covariance among the items and ¯v equals the average variance.
The increase number of items will increase Cronbanch's Alpha.
Additionally, if the average inter-item correlation is low, alpha will be low.
