Acertain county school district has 15 high schools. the high school seniors’ plans after graduation in each school vary greatly from one school to the next. the county superintendent will select a sample of high school seniors from the district to survey about their plans after graduation. the superintendent will use a cluster sample with the high schools as clusters. a random sample of 5 high schools will be selected, and all seniors at those high schools will complete the survey. what is one disadvantage to selecting a cluster sample to investigate the superintendent’s goal?

One disadvantage to selecting a cluster sample to investigate the superintendent’s goal is that the schools in the cluster sample might not be representative of the population of seniors

For better understanding let's explain what cluster sampling means

From the above we can therefore say that the answer One disadvantage to selecting a cluster sample to investigate the superintendent’s goal is that the schools in the cluster sample might not be representative of the population of seniors is correct

The downside is that clusters may not really be homogeneous between them.

Explanation:

Cluster sampling is a probabilistic sampling procedure in which population elements are randomly selected. Naturally by clusters. Cluster sampling helps us when it is impossible or impractical to create a sampling frame of a target population because it is geographically spread, as shown in the question above, and the cost of data collection is relatively high.

The main advantage of this technique is the operational part: selecting a cluster is often easier and cheaper than making a random or systematic sample. Using geographic clusters can represent significant savings in displacement.

The main disadvantage is the risk that clusters are not really homogeneous between them. In the example cited in the question above, it could happen that one of the schools is more prone to more seniors because it is a school with larger classes.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
