Higher Heart Rate (Pulse) Predicts Slightly Higher Facebook Pages Liked for Population

Facebook Pages Liked was generally 4% higher than average after an average of 99.2 beats per minute of Heart Rate over the previous 7 days.

Aggregated data from 4 study participants suggests with a HIGH degree of confidence (p=0.163, 95% CI -0.359 to 0.764) that Heart Rate has a weakly positive predictive relationship (R=0.202) with Facebook Pages Liked.

The highest quartile of Facebook Pages Liked measurements were observed following an average 108 beats per minute Heart Rate.

The lowest quartile of Facebook Pages Liked measurements were observed following an average 95.7 beats per minute of Heart Rate.

After an onset delay of 0 seconds, Facebook Pages Liked is typically 1% higher than average over the 7 days following around 95.7 beats per minute Heart Rate.

The objective of this study is to determine the nature of the relationship (if any) between Heart Rate and Facebook Pages Liked. Additionally, we attempt to determine the Heart Rate (Pulse) values most likely to produce optimal Facebook Pages Liked values.

This study is based on data donated by 4 participants. Thus, the study design is equivalent to the aggregation of 4 separate n=1 observational natural experiments.

Heart Rate (Pulse) Pre-Processing

Heart Rate (Pulse) measurement values below 20 beats per minute were assumed erroneous and removed. Heart Rate (Pulse) measurement values above 300 beats per minute were assumed erroneous and removed. No missing data filling value was defined for Heart Rate (Pulse) so any gaps in data were just not analyzed instead of assuming zero values for those times.

Facebook Pages Liked Pre-Processing

Facebook Pages Liked measurement values below 0 event were assumed erroneous and removed. No maximum allowed measurement value was defined for Facebook Pages Liked. It was assumed that any gaps in Facebook Pages Liked data were unrecorded 0 event measurement values.

Predictive Analytics

It was assumed that 0 seconds would pass before a change in Heart Rate (Pulse) would produce an observable change in Facebook Pages Liked.

It was assumed that Heart Rate (Pulse) could produce an observable change in Facebook Pages Liked 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 Facebook Pages Liked is not statistically significant at a 95% confidence interval. This suggests that the Heart Rate value does not have a significant influence on the Facebook Pages Liked value.

After treatment, a 22.1% increase (0.0971 event) from the mean baseline 0.475 event was observed. The relative standard deviation at baseline was 195.45%. The observed change was 0.551471 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).

Heart Rate (Pulse) data was primarily collected using Withings. Withings creates smart products and apps to take care of yourself and your loved ones in a new and easy way. Discover the Withings Pulse, Wi-Fi Body Scale, and Blood Pressure Monitor.

Facebook Pages Liked 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 weakly positive (R = 0.2023) relationship between Heart Rate (Pulse) and Facebook Pages Liked.

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. 712 paired data points were used in this analysis. Assuming that the relationship is merely coincidental, as the participant independently modifies their Heart Rate (Pulse) 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 Heart Rate (Pulse) and Facebook Pages Liked.

0 humans feel that any relationship observed between Heart Rate (Pulse) and Facebook Pages Liked 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
