Answer:Validity
Explanation:
Validity is measure of how valid the research is which means it gives solid relevant result which were initially intended. It is a test of how valid both your design and method of the research is.
There are various factors that can affect validity of the research.
There are internal factors that can affect validity of the research those are the ones that occur within the study such as failure to monitor vital variables of the study or using the inaccurate instrument to gather the needed data.
Below are the factors that has an impact on internal validity.
-size of the studied population
-instruments used
-history
-subject variability
-available time to gather data
- attrition
External validity are affected by the external factors such as the place where you conduct your research which may restrict the ability to obtain actual results . It can also be affected by the things like not being able to balance your subjects for example focusing on one gender and race eventhough your research is about all the types of people at large.
Crucial factors that affects external validity.
- The effect of time
- method use to collect data
- characteristics of the chosen population
- experiment effect
- interaction of subject selection
False
when we are absorbed in our thoughts and concerns we can't
focus on what someone else is saying is preoccupation. It is a big hindrance to
listening. Prejudgment is the tendency to judge others or their ideas before
we've heard them
.
The correct answer is; Plank.
Further Explanation:
North Carolina started building plank roads in the late 1840's. These roads were easier to maintain and easier to drive on. Before the plank roads were built, the roads had long muddy roads and large holes and ruts that drivers had to navigate through.
The crews could only lay an estimated 40 miles of plank roads per year and this did cause issues. North Carolina had the largest plank road with a total of 500 miles built. The rods failed after a few years because it took so long to build.
Citizens were then using the railroad system since it was faster than traveling by horse and buggy. The people also did not like having to stop at the toll booth that had been set up on the road. The money collected at the toll booth was used to pay for maintenance of the plank road.

Answer:
along a track in opposite directions.
Explanation:
In Economics, there are primarily two (2) factors which affect the availability and the price at which goods and services are sold or provided, these are demand and supply.
The law of demand states that, the higher the demand for goods and services, the higher the price it would be sold all things being equal.
On the other hand, law of supply states that the higher the price of goods and services, the lower the supply.
This ultimately implies that, there exist a negative relationship between the quantity of goods demanded and the price of a good. Thus, when the prices of goods and services in the market increases or rises: there would be a significant decline or fall in the demand for this goods and services.
According to the law of demand, price and quantity move along a track in opposite directions i.e the quantity of goods or services demanded is inversely proportional to the price of the goods or services at a specific period of time.
