    1. They found that people’s ability to detect road hazards, reaction time, and control of the vehicle were all impaired by cell phone use.

      The sentence is confusing and incorrectly structured

      confuse

    1. In physics, for example, one might measure the potential energy of an object in Earth’s gravitational field by finding its mass and height (which of course requires measuring those variables) and then multiplying them together along with the gravitational acceleration of Earth (9.8 m/s2).

      confusing

    1. 2 level designs and t-tests

      generally a confusing topic, you couldn't overexplain this enough

    2. A good rule of thumb, then, is that if it is possible to conduct a within-subjects experiment (with proper counterbalancing) in the time that is available per participant—and you have no serious concerns about carryover effects—this design is probably the best option. If a within-subjects design would be difficult or impossible to carry out, then you should consider a between-subjects design instead.

      Even if experimenters start with no serious concerns over carryover effects, it seems this can change over time. This to me feels like the hardest choice, because both have significant limitations. Finding the "best" design is difficult and sometimes hard to understand.

    1. Remember, that an issue with within-subjects designs is that subjects usually contribute data to each condition at different times or orders in the experiment. As a result, the order of the manipulation, rather than the manipulation itself, can sometimes cause differences. Counterbalancing is a technique used to systematically control the order in which subjects receive the manipulation.

      A bit confusing!

    1. My Tips

      After I did the symptom tracker, it took me right back to this page and the "Get Started". It seems like a prompt or direction of clicking on My Tips would be helpful to aid the user experience. I knew I should look at My Tips, but had momentarily forgotten as a pretend user.

    2. Get started Use the link below to begin.

      This seems misleading. I've just finished tracking my symptoms. Why is it prompting me to "get started". I see it says you can use it "as often as you'd like", but it seems that information would be helpful to bold or highlight or have closer to the top of paragraph.
