Sometimes, what appears to be a bimodal distribution is actuallytwo unimodal (one-peaked) distributions graphed on the same axis.For example, this image shows a bimodal distribution for a group of students who did not study (the left peak) and a group of students whodidstudy (on the right)...
Why is the median used for skewed data? Which distribution has the most peaks? a. A unimodal distribution b. A bimodal distribution c. A normal distribution d. A Gaussian distribution Give two examples of populations where the median would be the most appropriate indicat...
The first modern generative AI models, like ChatGPT, were considered unimodal; that is, they were only able to take one type of data as an input and generate the same type of output. In particular, most of these models were designed to process text prompts and generate a text response. ...
What role do z-scores play in the transformation of data from multiple distributions to the standard normal distribution? What z-score value separates the bottom 30% of the scores in a normal distribution from the top 70%? What is a critical z value...
The overall shape of a histogram is a visual representation of the data's distribution. Examining the shape allows analysts to identify crucial characteristics such as modality (unimodal, bimodal, or multimodal), symmetry, skewness, and the presence of gaps or spikes. Data distributions like normal...
Another important feature of foundation models is modality. Depending on the type of data foundation models can take as inputs, they can be unimodal or multimodal. The former can only take one type of data and generate the same type of output, while the latter can receive multiple modalities...
Symmetrical Distribution:Where both sides/tails of the distribution are symmetrical. In this category, the value of the skewness is 0. The mean, median, and mode are the same in a perfectly symmetrical (unimodal) distribution. Positively Skewed: Where the right side/tail of the distribution is...

What is CDF and PDF in statistics? What is the area under the standard normal distribution curve between z = 1.50, and z = 2.50? What makes the normal distribution a probability distribution? How to compare two Gaussian distributions? Which distribution has the most peaks? a. A unimodal di...
Distributions with only one such maximum are called unimodal; with two maxima, bimodal, and with more than two, multimodal. Mode How something is done or how it happens; Her dignified manner His rapid manner of talking Their nomadic mode of existence In the characteristic New York style A ...
