WebJul 8, 2024 · When data are skewed left, the mean is smaller than the median. If the data are symmetric, they have about the same shape on either side of the middle. In other words, if you fold the histogram in half, it looks about the same on both sides. Histogram C in the figure shows an example of symmetric data. With symmetric data, the mean and median ...

A distribution is symmetrical if a vertical line can be drawn at some point in the histogram … Webdata is not evenly partitioned across tasks. This type of skew, called data skew, typically affects reducers since map tasks are normally assigned same-size chunks of input data. For reducers, the problem can occur either when a reducer processes a larger number of keys or a larger number of values than other reducers. In our work,
