This is a statistical reasoning question A research group is comparing the learning outcomes of students who are taught a lesson using four different teaching techniques. There are 75 students in the school who can participate in the experiment. Using a table of random digits, the researchers will randomly place the students into five equally sized treatment groups suitable for comparison, four of which will receive a different teaching technique and one of which will remain a control group.

Which design is the most appropriate for this experiment?

Randomly number each person with 1, 2, 3, 4, or 5. Assign the students to the treatment groups based on their label.

Select a student, and identify the first digit reading from left to right on a random number table. If the first digit is 1 or 2, assign that student to the technique 1 group. Similarly, digits 3 or 4, 5 or 6, 7 or 8, and 9 or 0 go with the technique 2, technique 3, technique 4, and control groups, respectively. Repeat this process for each student.

Number each student from 1 to 75. Reading the numbers from left to right on a random number table, identify 60 unique numbers from 1 to 75. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.

Number each student from 00 to 74. Reading the numbers from left to right on a table of random numbers and looking at two digits at a time, identify 60 unique two-digit numbers from 00 to 74. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.

was making it through the muffling bag. I kept talking. "Listen—this is some kind of misunderstanding. We've got to get my friend to a hospital—" Someone went upside my head again. It felt like they used a baton or something—it was harder than anyone had ever hit me in the head before. My eyes swam and watered and I literally couldn't breathe through the pain. A moment later, I caught my breath, but I didn't say anything. I'd learned my lesson. In three to five sentences, explain Marcus' current stage of identity development. Use examples from the text.

It was a military-looking Jeep, like an armored Hummer, only it didn't have any military insignia on it. The car skidded to a stop just in front of me, and I jumped back and lost my balance and ended up on the road. I felt the doors open near me, and then saw a confusion of booted feet moving close by. I looked up and saw a bunch of military-looking guys in coveralls, holding big, bulky rifles and wearing hooded gas masks with tinted face-plates. I barely had time to register them before those rifles were pointed at me. I'd never looked down the barrel of a gun before, but everything you've heard about the experience is true. You freeze where you are, time stops, and your heart thunders in your ears. I opened my mouth, then shut it, then, very slowly, I held my hands up in front of me. The faceless, eyeless armed man above me kept his gun very level. I didn't even breathe. Van was screaming something and Jolu was shouting and I looked at them for a second and that was when someone put a coarse sack over my head and cinched it tight around my windpipe, so quick and so fiercely I barely had time to gasp before it was locked on me. I was pushed roughly but dispassionately onto my stomach and something went twice around my wrists and then tightened up as well, feeling like baling wire and biting cruelly. I cried out and my own voice was muffled by the hood. I was in total darkness now and I strained my ears to hear what was going on with my friends. I heard them shouting through the muffling canvas of the bag, and then I was being impersonally hauled to my feet by my wrists, my arms wrenched up behind my back, my shoulders screaming. I stumbled some, then a hand pushed my head down and I was inside the Hummer. More bodies were roughly shoved in beside me. "Guys?" I shouted, and earned a hard thump on my head for my trouble. I heard Jolu respond, then felt the thump he was dealt, too. My head rang like a gong. "Hey," I said to the soldiers. "Hey, listen! We're just high school students. I wanted to flag you down because my friend was bleeding. Someone stabbed him." I had no idea how much of this was making it through the muffling bag. I kept talking. "Listen—this is some kind of misunderstanding. We've got to get my friend to a hospital—" Someone went upside my head again. It felt like they used a baton or something—it was harder than anyone had ever hit me in the head before. My eyes swam and watered and I literally couldn't breathe through the pain.
