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.
I understand that she is a mother, so I would warn her. I would tell her to stop, and get her stuff together. Or else I, the parole officer, will get fired and you, the mother, will eventually get caught and sent back to prison. And if she wants the best for her kids, then find help for the stress, or find something that calms her down, nothing having to do with drugs or alcohol, of course. Something like painting, running, going for a walk, or writing it down in a journal to let it out. If she wants to stay with her kids, she will get her self together and fix her problems.
Which one? there is more than one.
It’s B, Dangerous air pollution
Cause
- oil spill , occurence where oil started to leak into other areas that inhabited by humans
- deforestation, an act to cut down a massive amount of trees without making and effeor to preserve it.
- leaky landfill, caused by companies who burried the waste of their production in the ground
- urbanization, lead to Pollution due to increase in vehilces
effect:
Contaminated water, which make people sick or even die after consuming it.
desertification, a situation where a land no longer usable for planting anything due to the desrtuction of its composition.
- smog, air pollutants created by factory smokes combined with fogs
