Database A contains 40 data itemsand is made up with an equal number of the values of 0 and 100 and has a mean of 50. Database B also has 40 entries made up equally of the values 49 and51 and also has a mean of 50. Which database will have the smaller value for its standard deviation?

Respuesta :

Answer:

A

Step-by-step explanation:

As the values are less spread, Database B will have a smaller value for the standard deviation.

  • In a data-set, the standard deviation is the square root of the sum of the differences squared between each observation and the mean, divided by the number of values.
  • The higher the standard deviation of the distribution, the more spread it is.

In this problem, we have two Databases, A and B. Both have mean of 50, wit A assuming values between 0 and 100 while B assumes values between 49 and 51. From this, we have that there is less spread in Database B, thus, it will have a smaller value for the standard deviation.
