their drilling samples
To investigate the evolution of ocean basins by core drilling of ocean sediments and underlying oceanic crust.
The data collected by the drilling ship Glomar Challenger confirmed continental drift.
The answer is Random Sample
The glass of water represents the drill bit, which is used to create a hole in the material being drilled. The straw represents the drill stem, which is the long, tubular component that connects the drill bit to the drilling rig. The empty glass represents the borehole, which is the hole that is created by the drilling process.

A core sample is a cylindrical sample of rock, soil, or ice that is obtained by drilling into the ground. It is used to study the composition, structure, and properties of the subsurface layers of the Earth. Core samples provide valuable information for various scientific disciplines, such as geology, environmental science, and archaeology.
Exploration by drilling will result in a core sample. Brought up inside the hollow drilling tubes, the core sample is pushed out and is laid out for inspection and study.
A biased sample is a Statistical Sample in which the sample is biased or have more samples of the things that is being influenced.
A sample is Unbiased if everyone in the sample have an equal chance of being selected
to cover up
That is the definition of a statistic
the space used to show a sample promblem.
Random Sample
A probability sample is one in which each member of the population has the same probability of being included. An alternative and equivalent definition is that it is a sample such that the probability of selecting that particular sample is the same for all samples of that size which could be drawn from the population.
A piece of a whole.
yes
There are two equivalent definition. Definition 1: A simple random sample is one for which each element has the same probability of being included in the sample. Definition 2: A simple random sample is one where all sample of that size have the same probability of being selected. Although the words are similar, the first refers to the selection of individuals from the population whereas the second refers to the samples.
