Higher Hip Circumference Predicts Moderately Lower Lack Of Motivation for Population

Lack of Motivation was generally 12.5% lower than average after 55 inches of Hip Circumference per 7 days.

Aggregated data from 1 study participants suggests with a LOW degree of confidence (p=0.369, 95% CI -1.923 to 0.975) that Hip Circumference has a moderately negative predictive relationship (R=-0.474) with Lack of Motivation.

The highest quartile of Lack of Motivation measurements were observed following an average 9.82 inches Hip Circumference.

The lowest quartile of Lack of Motivation measurements were observed following an average 16.9 inches of Hip Circumference.

After an onset delay of 0 seconds, Lack of Motivation is typically 8% lower than average over the 7 days following around 16.9 inches Hip Circumference.

The objective of this study is to determine the nature of the relationship (if any) between Hip Circumference and Lack of Motivation. Additionally, we attempt to determine the Hip Circumference values most likely to produce optimal Lack of Motivation values.

This study is based on data donated by 1 participants. Thus, the study design is equivalent to the aggregation of 1 separate n=1 observational natural experiments.

Hip Circumference Pre-Processing

Hip Circumference measurement values below 0 inches were assumed erroneous and removed. No maximum allowed measurement value was defined for Hip Circumference. No missing data filling value was defined for Hip Circumference so any gaps in data were just not analyzed instead of assuming zero values for those times.

Lack of Motivation Pre-Processing

Lack of Motivation measurement values below 1 out of 5 were assumed erroneous and removed. Lack of Motivation measurement values above 5 out of 5 were assumed erroneous and removed. No missing data filling value was defined for Lack of Motivation so any gaps in data were just not analyzed instead of assuming zero values for those times.

Predictive Analytics

It was assumed that 0 seconds would pass before a change in Hip Circumference would produce an observable change in Lack of Motivation.

It was assumed that Hip Circumference could produce an observable change in Lack of Motivation for as much as 7 days after the stimulus event.

Using a two-tailed t-test with alpha = 0.05, it was determined that the change in Lack of Motivation is not statistically significant at a 95% confidence interval. This suggests that the Hip Circumference value does not have a significant influence on the Lack of Motivation value.

After treatment, a 63.4% decrease (-0.321 out of 5) from the mean baseline 2.57 out of 5 was observed. The relative standard deviation at baseline was 30.6%. The observed change was 0.408529 times the standard deviation.

A common rule of thumb considers a change greater than twice the baseline standard deviation on two separate pre-post experiments may be considered significant. This occurrence would have only a 5% likelihood of resulting from random fluctuation (a p-value < 0.05).

Hip Circumference data was primarily collected using General Spreadsheet. Import from a spreadsheet containing a Variable Name, Value, Measurement Event Time, and Abbreviated Unit Name field. Here is an example spreadsheet with allowed column names, units and time format.

Lack of Motivation data was primarily collected using QuantiModo. QuantiModo allows you to easily track mood, symptoms, or any outcome you want to optimize in a fraction of a second. You can also import your data from over 30 other apps and devices. QuantiModo then analyzes your data to identify which hidden factors are most likely to be influencing your mood or symptoms.

As with any human experiment, it was impossible to control for all potentially confounding variables. Correlation does not necessarily imply causation. We can never know for sure if one factor is definitely the cause of an outcome. However, lack of correlation definitely implies the lack of a causal relationship. Hence, we can with great confidence rule out non-existent relationships. For instance, if we discover no relationship between mood and an antidepressant this information is just as or even more valuable than the discovery that there is a relationship.

We can also take advantage of several characteristics of time series data from many subjects to infer the likelihood of a causal relationship if we do find a correlational relationship. The criteria for causation are a group of minimal conditions necessary to provide adequate evidence of a causal relationship between an incidence and a possible consequence.

Criteria For Causal Inference

Strength (A.K.A. Effect Size)

A small association does not mean that there is not a causal effect, though the larger the association, the more likely that it is causal. There is a moderately negative (R = -0.474) relationship between Hip Circumference and Lack of Motivation.

Consistency (A.K.A. Reproducibility)

Consistent findings observed by different persons in different places with different samples strengthens the likelihood of an effect. Furthermore, in accordance with the law of large numbers (LLN), the predictive power and accuracy of these results will continually grow over time. 11 paired data points were used in this analysis. Assuming that the relationship is merely coincidental, as the participant independently modifies their Hip Circumference values, the observed strength of the relationship will decline until it is below the threshold of significance. To it another way, in the case that we do find a spurious correlation, suggesting that banana intake improves mood for instance, one will likely increase their banana intake. Due to the fact that this correlation is spurious, it is unlikely that you will see a continued and persistent corresponding increase in mood. So over time, the spurious correlation will naturally dissipate.

Specificity

Causation is likely if a very specific population at a specific site and disease with no other likely explanation. The more specific an association between a factor and an effect is, the bigger the probability of a causal relationship.

Temporality

The effect has to occur after the cause (and if there is an expected delay between the cause and expected effect, then the effect must occur after that delay). The confidence in a causal relationship is bolstered by the fact that time-precedence was taken into account in all calculations.

Biological Gradient

Greater exposure should generally lead to greater incidence of the effect. However, in some cases, the mere presence of the factor can trigger the effect. In other cases, an inverse proportion is observed: greater exposure leads to lower incidence.

Plausibility

A plausible bio-chemical mechanism between cause and effect is critical. This is where human brains excel.

Based on our responses so far,

0 humans feel that there is a plausible mechanism of action for a relationship between Hip Circumference and Lack of Motivation.

0 humans feel that any relationship observed between Hip Circumference and Lack of Motivation is coincidental.

Coherence

Coherence between epidemiological and laboratory findings increases the likelihood of an effect. It will be very enlightening to aggregate this data with the data from other participants with similar genetic, diseasomic, environmentomic, and demographic profiles.

Experiment

All of human life can be considered a natural experiment. Occasionally, it is possible to appeal to experimental evidence.

Analogy
