Which measure of dispersion indicates the extent to which each individual score in a data set varies from the mean of that set?
vichka [17]

Answer:

Option 2 - Standard deviation

Explanation:

To find : Which measure of dispersion indicates the extent to which each individual score in a data set varies from the mean of that set?

Solution :

Standard deviation is defined as,

  • It is a mathematical measure that is used to evaluate the difference between the mean value of a set of number and each value in the group.

A point charge is released from rest in a region containing an electric field. The charge will start to move
kotykmax [81]

Answer:

b) in a direction that makes its potential energy decrease.

Explanation:

  • As the electric field has the direction that would take a positive test charge under its sole influence, the positive test charge, will have an increase in its kinetic energy.
  • Due to the conservation of energy, in absence of non-conservative forces, this increment must be equal and opposite  to the  change in electric potential energy, which will be always negative, independent of the sign of the charge.
