Hindsight Biases01:12

Hindsight Biases

4.5K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Outliers and Influential Points01:08

Outliers and Influential Points

6.5K
An outlier is an observation of data that does not fit the rest of the data. It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500), while others may indicate that something unusual is happening. Outliers are present far from the least squares line in the vertical direction. They have large "errors," where the "error" or residual is the...

Crossing Over01:30

Crossing Over

6.9K
Crossing over is the exchange of genetic information between homologous chromosomes during prophase I of meiosis I. Genetic recombination gives rise to allelic diversity in the newly formed daughter cells. In humans, crossing over produces genetically distinct haploid egg and sperm cells that undergo fertilization to produce unique offspring. Before cell division starts, the germ cell’s chromosome(s) undergo duplication in the S phase of the cell cycle. As the cells enter prophase I,...

Crossing Over

173.3K
Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

Personal Choice and Fate Attributions01:19

Personal Choice and Fate Attributions

212
Some individuals interpret life events as a consequence of their personal choices and actions, while others believe that outcomes are dictated by fate or destiny. This divergence in perspective has been examined in psychological and cross-cultural studies, particularly in relation to religious faith and cultural beliefs about causality.Fate and Personal ResponsibilityPeople who emphasize personal responsibility view events as direct consequences of their decisions. For instance, breaking a leg...

What Are Outliers?01:12

What Are Outliers?

5.5K
Outliers are observed data points that are far from the least squares line. They have unusual values and need to be examined carefully. Though an outlier may result from erroneous data, at other times, it may hold valuable information about the population under study and should be included in the data. Hence, it is crucial to examine what causes a data point to be an outlier.
The z score is used to find outliers or unusual values. It should be noted that any values beyond -2 and +2 are...

    Area of Science:

    • Ophthalmology
    • Biomedical Engineering

    Background:

    • Accurate intra-ocular pressure (IOP) measurement is vital for diagnosing and managing glaucoma.
    • Malfunctioning diagnostic equipment can impede clinical workflow and diagnostic accuracy.

    Purpose of the Study:

    • To identify and resolve issues with an intra-ocular pressure measuring device.
    • To improve the reliability of audio feedback signals for proper instrument operation.

    Main Methods:

    • Investigated the audio output of the intra-ocular pressure device.
    • Compared the instrument's actual audio signals (clicks and beeps) against expected outputs.

    Main Results:

    • The intra-ocular pressure measuring instrument produced incorrect audio feedback.
    • Observed a reversal of expected click and beep signals.

    Conclusions:

    • The audio feedback system of the IOP device requires calibration or repair.
    • Resolving these signal discrepancies is necessary for correct instrument use in clinical settings.
