For a marketing research study to have validity, it must actually measure what it sets out to measure.
Explanation:
When it comes to research, we need to make sure that the measures we are using are reliable and valid.
Reliability refers to consistency across time, items, and researchers. Validity refers to what degree the results of the research reflect what they are intended to reflect (if the research actually measures what it has set out to measure). There are three main types of validity:
- face validity - the extent to which the research actually measures what it's supposed to measure;
- content validity - the extent to which a measure represents all aspects of the researched phenomenon;
- criterion validity - whether the results of the research correlate with other variables they are expected to be correlated with and not correlated with variables they are not expected to be correlated with.

Answer:
Move the decimal point two places to the right to find the product. To multiply a decimal number by a power of ten (such as 10, 100, 1,000, etc.), count the number of zeros in the power of ten. ... The multiplier 100 has two zeros, so you move the decimal point in 0.054 two places to the right—for a product of 5.4.

❄<u>Edwin Hubble made many important contributions to astronomy. Up until his observations in 1922, scientists were of the opinion that the universe consisted of only one galaxy: the Milky Way. Hubble's observations of Cepheids and subsequent measurement of their distances (using Henrietta Swan Leavitt's calculations) showed that many celestial objects were too far away to be part of the Milky Way and were actually galaxies themselves.❄</u>
<u>❄By calculating the distances to many newly found galaxies, Hubble also discovered that the galaxies were receding away from Earth and that the speed of recession was proportional to the distance. This established the fact that the universe was expanding, which changed the entire consensus (from the time of Newton) that the universe was finite. It also backed up Georges Lemaître's theory that the universe had a beginning (later called the Big Bang).❄</u>
