Time Series Analysis

14.1. INTRODUCTION

The term �Time Series� consists of quantitative data which are arranged in the order of their occurrence. For example when we collect the data regarding population per capita income, sales and prices of a commodity, etc. for a particular time period and arrange the data so obtained in a series, called time series. Thus, according to �Spiegel�.

�A time series is a set of observations taken at specified times, usually at equal intervals.�

In the analysis of time series, time is the most important variable which may be either year, month, week, day, hour or even minutes or seconds.

14.2. SIGNIFICANCE OF TIME SERIES ANALYSIS

(P.T.U., M.B.A. Dec. 2012)

The analysis of time series is of great importance because of the following reasons.

(a) To understand past behaviour. With the help of time series analysis, we can observe data over a period of time and easily understand the changes which have taken place in the past. This helps us in predicting the future behaviour.

Chapter 5 Integrating Assessment and Intervention

Chris Weber Solution Tree Press ePub

Success in mathematics is a moral imperative and “algebra is a civil right” (Moses, 2001, p. 5). If educators do not believe in each student’s ability to master mathematics concepts and procedures, then we would have to consider why we are bothering to intervene. We must accept that some students will simply require alternative strategies to learn, that not every student will learn the same way, and that some students will require additional time. We must also believe in our ability to teach every student. A teacher’s sense of self-efficacy significantly predicts the achievement of students, and elementary school teachers’ beliefs in their abilities to teach mathematics lag far behind their beliefs in teaching reading well (Ashton & Webb, 1986; Bandura, 1993; Coladarci, 1992; Dembo & Gibson, 1985). We must also believe, and communicate to students, that mathematics achievement is not dependent on innate ability; work ethic, effort, perseverance, and motivation exert a significant impact on learning (Duckworth, Peterson, Matthews, & Kelly, 2007; Dweck, 2006; Seligman, 1991).
