Doyle complied and eventually wound up writing fifty-six short stories and four novels that featured Holmes. Together with his partner, Dr. Watson, Holmes uses his powers of observation to detect clues that can help him solve the cases 1i he accepts.

Holmes has an incredibly sharp mind that enables him to determine who the guilty party is or whdt the problem is. Holmes also is a master ofdisguise, which he proves many times, and he is skilled at boxing as well as sword fightjng.

About Mr. The solid curve in each frame is the estimated mean score on the first test administration as a function of interval, while the dashed curve is the estimated mean score on the second test administration as a function of interval. Figure 3 Open in figure viewer PowerPoint Smoothed trends of initial score solid line and second administration score dashed line as a function of interval, separately for each skill area and the total.

As shown in Figure 3 , the distance between the dashed and solid curves, representing average score gains, tends to increase as the interval increases. Generally, the effect is modestly evident from the low end of the interval distribution to the middle and very evident at the higher end of the interval distribution, consistent with Table 2 , in which the interval was treated as a categorical variable.

The two curves start to diverge at an interval of about days, and this pattern is consistent for all subtests. This explained why the average interval was much longer for this group. Although these students may constitute a distinct population, they do not differ much from students in other countries with respect to overall initial score. Hierarchical Linear Models The descriptive information is consistent with the hypothesis that the test is sensitive to changes in English ability as a function of interval.

The main motivation for conducting HLM analyses was to quantify the relationship between interval and gains in a way that would not be distorted by potential differences in student populations across countries and to obtain a valid test of statistical significance of this relationship. Our HLM is designed to achieve both of these goals. We first present what we call the base model and then present what we call the alternative model, which we use to address a particular potential source of bias in the base model.

The effect of interest is the coefficient on interval. All other effects in the model are included only to improve the estimate of the effect of interval and to get an appropriate measure of uncertainty about this effect. We now describe these other effects and why they should achieve these goals. We include dummy variables in the model for individual countries to prevent country differences from biasing our estimated relationship between interval and gains.

As noted previously, there were large differences in the distributions of interval across countries, especially at the higher end of the interval distribution. These differences could have led to bias in the estimated relationship between interval and score gains if students from different countries had systematically different average values of interval because of unobserved test taker characteristics that were related to score gains. It seemed reasonable to assume that such characteristics might exist, so we needed to treat differences among countries as a potential confounding factor and find a way to prevent this potential confounding factor from biasing the estimated coefficient on interval.

Treating countries as dummy variables avoids this potential confounding, as it ensures that the effect of interval is estimated using only variation in interval among students but within countries i.

Differences in the average value of interval across countries do not therefore contribute to the estimated effect of interval, and therefore, differences among students in different countries cannot be a source of bias.

We include random effects in the model for testing groups. By definition, students in the same testing group had the same interval; thus, it was not possible to include dummy variables for testing groups because that would have left no variation with which to estimate the effect of interval.

However, it was possible to include random effects for testing groups. Doing so is beneficial and important. As described earlier, students belonging to the same testing group were likely to share similar instructional or testing experiences. These factors could have caused students who shared a testing group to have systematically higher or lower gains than would have been predicted based on only the interval and the country for that group.

The testing group random effects are introduced to account for unobserved differences in the average gains in different testing groups that remain after accounting for both interval and country effects. Accounting for this variation through the random effects leads to a more accurate estimate of the effect of interval and an accurate standard error for this estimated effect. Our model assumes a linear relationship between interval and gains within countries.

It is reasonable to question whether a nonlinear relationship would be more appropriate. The linear specification is also supported by a graphical analysis. Figure 4 provides a scatterplot of total gains versus interval where both quantities are centered by their respective country means. This represents the relationship between total gains and interval within countries, aligning closely to how Model 1 identifies the effect of interval through the use of country dummy variables.

The fact that these two curves nearly coincide supports the assumption that the relationship between gains and interval within country is well approximated by the linear specification of Model 1.
