How To Go About Collecting Sample Data

Things to consider when collecting sample data

If the sample data we collect is not collected appropriately, the data we gather may be completely useless.

An observational study allows us to measure certain characteristics, but we don’t modify the subjects which are being studied.

In an experiment we apply a treatment, then we observe its effects on a subject.

Types of Data in Statistics, Some Examples, and Statistics Definitions (Intro to Stats)

Types of Data

Parameter – this is always a numerical measurement which describes a characteristic of a population.

Statistic – this is always a numerical measurement which describes a characteristic of a sample.

Though these both may sound similar, a parameter and statistic are not the same at all except for the fact they are both numerical measurements. Since they sound similar it would prove wise to provide a couple of examples to make sure we understand the difference between the 2.

A survey concerning reading ebooks vs printed books

Surveys usually help us in improving or making adjustments to products or services. As well as to educate and attempt to explain questions. These may shape different aspects of our life. Surveys allow us to learn the insights and opinions of other people. One survey conducted by USA Today wanted to see if people prefer printed books over electronic ones. There were 281 respondents of which 35% preferred electronic books, while 65% preferred printed books. This survey may seem to suggest that most people rather read printed books than ebooks.

What are the different ways to study sexuality?

Bio-Medicine

Bio-medical research looks at the mechanism underlying sex. Research in bio-medicine has the most impact which is most practical concerning the sex lives of individuals. These include drug treatment (concerning reproductive cancers), hormone-based abortion and contraception, technologies that treat infertility, methods to prevent STIs, etc.

Biology Notes Introduction to Life

What my Intro to Biology Study Guide Looks Like

Identify and describe the properties of life.  – Living things share some common properties. According to our online reading material the properties of life are order, sensitivity or response to stimuli, reproduction, adaption, growth and development, regulation, homeostasis, and energy processing.  These 8 characteristics characterize living things.  Life displays order through the organization of the organism.  Living things will either respond positively or negatively to stimuli.  Then, there is reproduction. which single-celled organisms are able to do by copying and duplicating its DNA. Once the information is copied it divides equally, while many multi-celled organisms produce special reproductive cells that form new individuals. DNA, which contains the genetics, are passed down to offspring after reproduction  Adaptation has to do with how a living organism “fits” into their environment and the process of natural selection allows for organisms to change accordingly to that environment.  Though adaption is not constant, whenever there are changes in the environment, the population of that environment will change to maximize their reproductive potential in accordance with those new changes. Growth and development is an obvious sign of something living and it happens based on the genes which were passed by the parents.  The regulation of all these complex processes happens constantly while that organism remains alive.  Even small organisms need a mechanism to coordinate and regulate internal functions. Homeostasis allows an organism to keep a constant internal state or “steady-state”.  A polar bear, for example, keeps homeostasis through a process called thermoregulation.  Last is energy processing.  All living organisms use a source of energy.  Energy allows for metabolic activities to happen.  Some organisms get their energy from the sun which is changed and converted into chemical energy.  Other organisms get their energy from molecules taken in.
