Response Variable and Explanatory Variable. Example One To explore these concepts we will examine a few examples. For the first example, suppose that a researcher is interested in studying the mood and attitudes of a group of first year college students. All first year students are given a series of questions. These questions are designed to assess the degree of homesickness of a student. Students also indicate on the survey how far their college is from home. One researcher who examines this data may just be interested in the types…

## Linear Algebra – Post 2 – Linear combination & Span , Linear Dependence & Linear Independence

Linear Combination and Span: Given a set of vectors, what other vectors can you create by adding and/or subtracting scalar multiples of those vectors. The set of vectors that you can create through these linear combinations of the original set is called the “span” of the set. More generally, a linear combination of n vectors v1, v2, . . . , vn is any vector of the form a1v1 + a2v2 + · · · + anvn where a1, a2, . . . , an are scalars The set of…
