One can take elementary statistics courses via the UDACITY website. One can enroll by simply clicking on the 'Take the Class' link. UWC Online offer a similar course.
It depends on which type of scientist and the specific field. Thus, one should consider higher level math courses, to include calculus and statistics.
ALEKS offer math courses to elementary school students. They have algebra, graphs, geometry, decimal numbers and fractions as part of the course. One can register with them online.
There are many courses at Macalester college for one to choose from. However, they are very well know for their Mathematics, Statistics and Computing courses. There are other courses available though.
One can find a course for learning details on online statistics by going to the CMU website. Another place to find courses for learning details on statistics is the Berkeley website.
To teach at the secondary level or higher you really need a math major although you can be certified in most states with a minor in math and can likely get a job since math teachers are relatively scarce. You need to take the education courses needed for certification if you want to teach in a public school. You can teach math at the elementary level after one or two courses in math for elementary education. At any level, you will find it advantageous to take as many math courses as you can.

Correspondence courses, or home study courses allow you to take college courses at home without the need to attend lectures at a college campus. An example of an organisation that offers college courses that can be taken at home is the Open University.
The courses you can take really depend in the High School you are in (I will assume that you are referring to High School Courses). After algebra, most schools allow Pre Calculus. Pre Calculus is basically just like algebra two, just with more trigonometry and deeper exploration of math. Then, one can take the flower of math, Calculus. In schools that offer Advance Placement (AP) courses, will offer AP Calculus AB and AP Calculus BC. Calculus was divided into parts, here A, B and C. I have heard of a D section, but is not taught in many high schools. Separate from the Calculus course tree we have statistics. One can take statistics, followed by AP Stats. (One might be able to skip statistics should they be competent enough for AP Stats.) There is also a branch of Math called Discrete Mathematics, that concerns mostly on logic, that is separate from other math course tree.There could be other math courses, such as Further Mathematics, but the courses stated above are the most common courses offered.
There are several online sources to take courses to become a surgical tech. Courses are also offered at local colleges and universities.
