These outliers will skew the result too much *The median CAN be best method when outliers are present because while it takes account all of the numbers/data. Unlike the mean, the median does not necessarily rely on the values of each individual number that it is counting giving us the most accurate central tendency *The mode is only the best measure when you want to know what is the most popular choice amongst the dataset. Otherwise - the mode is not the most dependent measure of central tendency Percentile score - Answer-A percentile score of 75% would indicate that that student did as well or better than 75% of the total test taker population Stanine Scores - Answer-A 9 POINT SCALE each # (1-9) representing a wide range of raw scores 1-3, below 4-6 average, 7-9 above average grade equivalent score - Answer-At what grade level did students achieve that particular (RAW) scare Test score indicating the grade level of students to whom a test taker performed most similarly. Recognizing Equivalent Methods of Problem Solving - Answer-Strategy 1: Make sure that the answer given matches the original value (for example: OG= 2x ans= 2(x)) Strategy 2: SIMPLIFY the original expression given in the problem Express the FRACTION 5/16 as a PERCENTAGE rounded to the nearest hundredth. - Answer-set 5/16 = x/100 Cross multiply 16x = 500 Isolate x 500/16 solve dimensions v area - Answer-Dimension refers to EXACT # VALUE Area refers to STRICTLY the end product, not including value
