Treatment 1 Treatment 2
6 19
13 9
8 18
4 10
13 12

Which variables are described in this scenario and what are their scales of measurement? Which test should you use?
The following data are obtained from a study that seeks to investigate theeffects of an intervention program and the extent of their physical disability on their reading, math and IQ scores. The students who had been recipients of an intervention program are in the treatment group and while those who are not are in the control group.
Questions:1. Is there a significant difference in the math, reading and IQ scores ofstudents in the treatment and controlgroups?2. Is the intervention program effective?3. Is there a significant difference in the math, reading and IQ scores ofstudentswhen they are grouped according to the extent of their physicaldisability?4. Isthereasignificantinteractionbetweentreatmentandextentofdisabilityonthe students’ reading, math and IQscores?
The following data were collected from a repeated-measures study. Determine if there are any significant differences among the four treatment conditions. Use the .05 level of significance.
