+<p>The general formula for a confidence interval is <span class="math inline">\(point~estimate~±~z^*\times~SE\)</span>. First, identify the three different values. The point estimate is 45%, <span class="math inline">\(z^* = 2.58\)</span> for a 99% confidence level (that’s the number of standard deviations around the mean that ensure that 99% of a Z-score distribution is included), and <span class="math inline">\(SE = 2.4\%\)</span>.</p>
+<p>With this we can plug and chug:</p>
+<p><span class="math display">\[52\% ± 2.58 \times 2.4\% → (45.8\%, 58.2\%)\]</span></p>

+<li><p>False. The standard error of the sample does not contain any information about the proportion of the population included in the sample. It measures the variability of the sample distribution.</p></li>
+<li><p>False. Increasing the sample size will decrease the standard error. Consider the formula: <span class="math inline">\(\frac{\sigma}{\sqrt{n}}\)</span>. A smaller <span class="math inline">\(n\)</span> will result in a larger standard error.</p></li>
+<li><p>False. All else being equal, a lower confidence interval will cover a narrower range. A higher interval will cover a wider range. To confirm this, revisit the formula in SQ1 above. and plug in the corresponding alpha value of .9, resulting in a <span class="math inline">\(z^*\)</span> value of 1.28 (see the Z-score table in the back of <em>OpenIntro</em>).</p></li>

+<p>The hypotheses should be about the population mean (<span class="math inline">\(\mu\)</span>) and not the sample mean (<span class="math inline">\(\bar{x}\)</span>).

+<li>False. A lower alpha value is the probability of Type 1 Error, so reducing the one reduces the other.</li>

+<li>True. Consult the section of <em>OpenIntro</em> discussing statistical power and Type 2 Error.</li>
+<li>True. We’ll revisit this in a moment below, but consider the relationship between statistical test, the standard error, and the sample size. As the sample size increases towards infinity, the standard error approaches zero, resulting in arbitrarily precise point estimates that will result in rejecting the null hypothesis for <em>any</em> value of a test statistic for any critical value of <span class="math inline">\(\alpha\)</span>.</li>

+<h2>EQ1</h2>
+<p>In my words (or rather formulas since I think that’s less ambiguous), the key pairs of null/alternative hypotheses look something like the following:</p>
+<p>Let <span class="math inline">\(\Delta\)</span> be the parameter estimate for the difference in mean percentage of positive (<span class="math inline">\(\mu_{pos}\)</span>) and negative (<span class="math inline">\(\mu_{neg}\)</span>) words between the experimental and control conditions for the treatments of reduced negative content (<span class="math inline">\(R_{neg}\)</span> and reduced positive content (<span class="math inline">\(R_{pos}\)</span>).</p>
+<p>For the reduced negative content conditions (the left-hand side of Figure 1), the paper tests:</p>
+<p><span class="math display">\[HR_{neg}1_0: \Delta_{\mu_{pos}} = 0\]</span> <span class="math display">\[HR_{neg}1_a: \Delta{\mu_{pos}} \gt 0\]</span> And: <span class="math display">\[HR_{neg}2_0: \Delta_{\mu_{neg}} = 0\]</span> <span class="math display">\[HR_{neg}2_a: \Delta_{\mu_{neg}} \lt 0\]</span> Then, for the reduced positive content conditions (the right-hand side of Figure 1), the paper tests:</p>
+<p><span class="math display">\[HR_{pos}1_0:~~ \Delta_{\mu_{pos}} = 0\]</span> <span class="math display">\[HR_{pos}1_a:~~ \Delta{\mu_{pos}} \lt 0\]</span></p>
+<p>And:</p>
+<p><span class="math display">\[HR_{pos}2_0:~~ \Delta_{\mu_{neg}} = 0\]</span> <span class="math display">\[HR_{pos}2_a:~~ \Delta_{\mu_{neg}} \gt 0\]</span> Note that the theories the authors used to motivate the study imply directions for the alternative hypotheses, but nothing in the description of the analysis suggests that they used one-tailed tests. I’ve written these all in terms of specific directions here to correspond with the theories stated in the paper. They could also (arguably more accurately) have been written in terms of inequalities (“<span class="math inline">\(\neq\)</span>”).</p>

+<p>The authors’ estimates suggest that reduced negative News Feed content causes an increase in the percentage of positive words and a decrease in the percentage of negative words in subsequent News Feed posts by study participants (supporting <span class="math inline">\(HR_{neg}1_a\)</span> and <span class="math inline">\(HR_{neg}2_a\)</span> respectively).</p>
+<p>They also find that reduced positive News Feed content causes a decrease in the percentage of negative words and an increase in the percentage of positive words in susbequent News Feed posts (supporting <span class="math inline">\(HR_{pos}1_a\)</span> and <span class="math inline">\(HR_{pos}2_a\)</span>)</p>

+<p>Cohen’s <span class="math inline">\(d\)</span> puts estimates of experimental effects in standardized units (much like a Z-score!) in order to help understand their size relative to the underlying distribution of the dependent variable(s). The d-values for each of the effects estimated in the paper are 0.02, 0.001, 0.02, and 0.008 respectively (in the order presented in the paper, not in order of the hypotheses above!). These are miniscule effects. However, the treatment itself is also quite narrow in scope, suggesting that the presence of any treatment effect at all is an indication of the underlying phenomenon (emotional contagion). Personally, I find it difficult to attribute much substantive significance to the results because I’m not even convinced that tiny shifts in the percentage of positive/negative words used in News Feed updates accurately index meaningful emotional shifts (maybe we could call it linguistic contagion instead?). Despite these concerns and the ethical considerations that attracted so much public attention, I consider this a clever, well-executed study and I think it’s quite compelling. I expect many of you will have different opinions of various kinds!</p>
