Want this question answered?
negative 8 is greater
In the same way that you calculate mean and median that are greater than the standard deviation!
No. Negative 15 is greater than negative 33.
-5 is greater.
-3 is greater
Most of the mechanisms in our body are regulated by negative feedback inhibition. In this type of process, the end product shuts off or reduces the intensity of the original stimulus. Production of certain hormones when mother is giving birth to a child is regulated by positive feedback inhibition. In this type of process, response leads to an even greater response.
Yes. It can have any non-negative value.
An example of negative feedback would be a secretion of greater amount of insulin to lower the blood sugar level, and then secretion of greater amount of glucagon to increase the blood sugar level, and then a secretion of a greater amount of insulin to lower the blood sugar level..... etc.
The answer depends on greater standard deviation that WHAT!
Standard deviation can be greater than the mean.
Standard deviation is a measure of the dispersion of the data. When the standard deviation is greater than the mean, a coefficient of variation is greater than one. See: http://en.wikipedia.org/wiki/Coefficient_of_variation If you assume the data is normally distributed, then the lower limit of the interval of the mean +/- one standard deviation (68% confidence interval) will be a negative value. If it is not realistic to have negative values, then the assumption of a normal distribution may be in error and you should consider other distributions. Common distributions with no negative values are gamma, log normal and exponential.
It does not indicate anything if the mean is greater than the standard deviation.
Punishment is not a reinforcer. there is Negative Punishment and Positive Punishment, and also Negative Reinforcement and Positive Reinforcement.*Negative Punishment is a consequence withdrawn following a response that causes a behavior to occur with less frequency.*Negative Reinforcement is a consequence withdrawn following a response that causes a behavior to occur with greater frequency.*Positive Punishment is a consequence delivered following a response that causes a behavior to occur with less frequency.*Positive Reinforcement is a consequence delivered following a response that causes a behavior to occur with greater frequency.
In general, a mean can be greater or less than the standard deviation.
The standard deviation must be greater than or equal to zero.
Most homeostatic control mechanisms are negative feedback mechanisms. In such systems, the net effect of the response to the stimulus is to shut off the original stimulus or reduce its intensity. or in simpler terms its just feedback that causes the stimulus to decline or end.
Positive feedback speeds up reactions and negative feedback slows them down. In electronics and control systems, positive feedback means the feedback gets added to the input and then goes as output. And negative feedback means that the output is input minus feedback (from output). This is the most basic and layman answer I can think of. In social and business terms, a positive feedback means a good response ( a praise for a product, or interest generation among the clients) and a negative feedback means a bad response (unhappy clients, criticism and the like ).
