What is the standard deviation of a sampling distribution called?

GarryVolchara [31]

Answer: Standard error.

Step-by-step explanation:

If the population is normally distributed , then the standard deviation of a sampling distribution of the sample mean $[tex]\overline{x}$ [/tex] is known as standard error which depends on population standard deviation $(\sigma)$ and the sample size (n).

$\sigma_x=\dfrac{\sigma}{\sqrt{n}}$

It measure the variability in the sample statistics that happens by chance.

Thus, the standard deviation of a sampling distribution is called the <u>standard error</u>.

A research report from an independent-measures study states that there are significant differences between treatments, F(3, 48)

Flura [38]

Answer:

k = 4 ;

N = 52

Step-by-step explanation:

Given the ratio F(3, 48)

F takes in degree of freedom values; degree of freedom of groups ; degree of freedom of error

Hence,

df group or treatment = 3

df error = 48

df treatment = k - 1

k = Number of groups

3 = k - 1

3 + 1 = k - 1 + 1

4 = k

Number of treatment condition = 4

df error = N-k

N = total number of observations

48 = N - 4

48 + 4 = N - 4 + 4

52 = N

Give the following equations determine if the lines are parallel perpendicular or neither

GaryK [48]

In order to determine whether the equations are parallel, perpendicular, or neither, let's simply each equation into a slope-intercept form or basically, solve for y.

Let's start with the first equation.
