the number of steps per day is said to be related to fitness level (as measured with vo2 testing). which type of validity is des
taurus [48]

The term "concurrent validity" refers to the relationship between step count with vo2 data.

<h3>Define the term concurrent validity?</h3>
  • The degree of agreement between two measurements or assessments made at the same time is displayed by concurrent validity.
  • It contrasts a brand-new test with one that has already undergone testing and been shown to be reliable.

You wish to evaluate a new survey that measures employee commitment's concurrent validity. In order to accomplish so, you may:

  1. Ask the same group of employees to respond to your new survey as well as an earlier (validated) survey. then contrast the outcomes.
  2. Obtain some staff responses to your new survey. The findings of a popular employee performance indicator, including a performance evaluation, should then be compared to the respondents' responses.

There is a connection between daily step count and fitness level (as collected with vo2 testing)

Thus, the term "concurrent validity" refers to the relationship between step count with vo2 data.

x = 30 * 1 : 5/6
x = 30 : 5/6
x = 30 * 6/5
x = 36

Anika [276]

Answer:

1413.86 ft^2.

Step-by-step explanation:

The diameter of the circle = 50 - 2(18)

So its radius is 7 ft.

The total area of the blue shape
