When was the first exploration of the Bathypelagic zone?
The first exploration of the Bathypelagic zone, which ranges from about 1,000 to 4,000 meters deep in the ocean, occurred during the late 19th century. Notably, the HMS Challenger expedition from 1872 to 1876 provided significant insights into deep-sea environments, including the Bathypelagic zone. This expedition collected valuable data on marine life, sediment samples, and oceanographic conditions, marking a pivotal moment in ocean exploration.
Do marine biologists spend time in labs?
Yes, marine biologists spend time in labs conducting experiments, analyzing samples, and studying data collected from the field. They use lab work to further their understanding of marine ecosystems and the organisms living within them.
What is the mean of biological sense?
In a biological context, "mean" typically refers to the average value of a set of data points. It is used to summarize and compare quantitative observations within a population of organisms or biological samples. Calculating the mean helps researchers understand central tendencies and variation in biological phenomena.
Did Richard Byrd bring back anything from Antarctica?
Yes, Richard Byrd brought back scientific data, photographs, and specimens from his expeditions to Antarctica. He collected valuable information about the continent's geography, climate, and wildlife, which contributed to a better understanding of this remote region.
What data did Charles Darwin anilize?
Charles Darwin analyzed a wide range of data, including observations of species during his voyage on the HMS Beagle, particularly in the Galápagos Islands. He collected and studied specimens of plants and animals, noting variations and adaptations in different environments. Additionally, he examined fossil records and geographical distributions of species, which contributed to his formulation of the theory of natural selection. His extensive correspondence and research on animal breeding also informed his understanding of variation and inheritance.
What is the definition data?
Information obtained from experiments. (information collected from an experiment)
How is data collected in statistics?
data can be collected many different ways, but a survey can be cunducted in a few different ways some of them are: simple random, stratified, block samples stratified simple random
How to test data using SPSS?
You can test data using T-Test in SPSS. Click Analyze > Compare Means > Independent-Samples T-Test to run an Independent Samples T-Test in SPSS. In the Independent-Samples T-Test window, you specify the variables to be analyzed. On the left side of the screen, you will see a list of all variables in your dataset.
What does first hand data and second data do?
First-hand data is collected directly from the original source, while second-hand data is obtained from sources that have already collected and reported the data. First-hand data is considered more reliable and accurate, as it is obtained firsthand. Second-hand data may be useful when primary data is not available or when researchers want to conduct secondary analysis.
Definition of independent sample.?
two samples are independent if they are drawn from two different populations, and/ or the samples have no effect on each other. eg: We want to estimate the difference between the mean salaries of all male and all female executives. We draw one sample from the population of male executives and another from the population of female executives. These two samples are independent because they come from different populations and the samples have no effect on each other
What is primary data in maths term?
Data that you yourself have collected (or commissioned their collection), rather than obtained from some other source.
What is Independent Sampling?
Data gathered i n two different samples such as the sample data drawn from one population is completely unrelated to the section of sample data,
Would the resulting sets of data represent dependent or independent samples?
dependent. because this set of numbers is dependent on what is put into the data table.
What experiments do geologists conduct?
I suppose hardness and density tests on rock samples. Making seismic soundings and measuring the results, analyzing the data collected.
Explain the difference between primary data and secondary data give an example of each?
Primary data is data collected firsthand, through surveys, interviews, experiments, etc. by the researcher, while secondary data is existing data that has already been collected by someone else. An example of primary data would be survey responses collected by a marketing team for a new product. An example of secondary data would be industry reports or census data obtained from a government website.
What did the Apollo 11 crew do on the moon?
They collected samples, took pictures, reported back via radio what their impressions were, and placed science packages out to collect data.
What is the difference between primary data and secondary data?
primary data is data which has been collected by yourself, which is more reliable and up to date. secondary data has been collected from a secondary source (Other people, business etc.) so it may not be valid or up to date
