When data is skewed to the left, it means that the bulk of the data points are concentrated on the right side of the distribution, with a longer tail extending towards the left. This results in a mean that is typically less than the median, indicating that there are a few lower values that pull the average down. Left skewness often reflects the presence of outliers or lower values in the dataset. Visual representations, like histograms, will show this characteristic as a peak to the right with a tapering off to the left.
To determine if the data in a line plot is skewed left, right, or not skewed, you would need to observe the distribution of the data points. If the tail on the left side is longer or fatter, it is left-skewed; if the tail on the right side is longer or fatter, it is right-skewed. If the data points are evenly distributed around a central value, it is not skewed. Without seeing the actual plot, I can't provide a definitive answer.
When the majority of the data values fall to the right of the mean, the distribution is indeed said to be left skewed, or negatively skewed. In this type of distribution, the tail on the left side is longer or fatter, indicating that there are a few lower values pulling the mean down. This results in the mean being less than the median, as the median is less affected by extreme values. Overall, left skewed distributions show that most data points are higher than the average.
In left-skewed data, the distribution has a longer tail on the left side, which pulls the mean down more than the median. The mean is affected by extreme low values, leading it to be lower than the median, which represents the middle value of the dataset and is less influenced by outliers. As a result, in left-skewed distributions, the mean lies to the left of the median.
In mathematics, "skewed" refers to the asymmetry in the distribution of data. A skewed distribution can be either positively skewed, where the tail on the right side is longer or fatter, or negatively skewed, where the tail on the left side is longer or fatter. This indicates that the mean and median of the data may not align, often with the mean being pulled in the direction of the skew. Understanding skewness helps in analyzing the characteristics of the data and choosing appropriate statistical methods.
Unimodal skewed refers to a distribution that has one prominent peak (or mode) and is asymmetrical, meaning it is not evenly balanced around the peak. In a right (or positively) skewed distribution, the tail on the right side is longer or fatter, indicating that most data points are concentrated on the left. Conversely, in a left (or negatively) skewed distribution, the tail on the left side is longer, with most data points clustered on the right. This skewness affects the mean, median, and mode of the data, typically pulling the mean in the direction of the tail.
The population data may be skewed and thus the mean is not a valid statistic. If mean > median, the data will be skewed to the right. If median > mean, the data is skewed to the left.

A positively skewed or right skewed distribution means that the mean of the data falls to the right of the median. Picturewise, most of the frequency would occur to the left of the graph.

on the left and when it is skewed left it is on the right

skewed
i) Since Mean<Median the distribution is negatively skewed ii) Since Mean>Median the distribution is positively skewed iii) Median>Mode the distribution is positively skewed iv) Median<Mode the distribution is negatively skewed
If it is very highly skewed then the mode is best.
