Measures of central tendency (mean, median, midrange, mode), illustrating frequency distributions (histogram, pie charts, ogive, box plot), and measures of dispersion (range, deviation from mean, variance, standard deviation), as well as ideas such as sample vs. population data, etc. really are very straight-forward concepts and all are very useful tools in statistics.
Your statistics course is divided into two main sections --- descriptive statistics (see the concepts above) and then inferential statistics.
Don't just "skim over" the easy, beginning stuff as you will see it all again when you get to the more challenging chapters.
