How can you use box plots to compare two data sets?
Box plots are effective for comparing two data sets by visually displaying their key statistical measures, such as median, quartiles, and potential outliers. By plotting both data sets on the same scale, you can easily see differences in their central tendencies, variability, and distribution shapes. This allows for quick comparisons of data characteristics, such as whether one set has a higher median or greater spread than the other. Additionally, the presence of outliers in each data set can be assessed at a glance.
Can outliers affect the symmetry of the data?
an outliers can affect the symmetry of the data because u can still move around it
What are the benefits of representing data sets using frequency distribution?
Representing data sets using frequency distribution provides a clear and organized way to summarize and visualize data, making it easier to identify patterns and trends. It allows for quick assessment of the data's distribution, facilitating comparisons between different data sets. Additionally, frequency distributions help in identifying outliers and understanding the shape of the data, which can inform further statistical analysis and decision-making.
What is the term that is used to describe data that does not fit with the rest of the data?
Outliers
If a data set has many outliers which measure of central tendency would be the BEST to use?
In a data set with many outliers, the median is the best measure of central tendency to use. Unlike the mean, which can be significantly affected by extreme values, the median provides a more accurate representation of the central location of the data. It effectively divides the data into two equal halves, making it robust against outliers. Therefore, the median offers a clearer understanding of the typical value in such cases.
What is the primary disadvantage of using the range to compare the variability of data sets?
The range is very sensitive to outliers. Indeed if there are outliers then the range will be unrelated to any other elements of the sample.
Can there be 2 outliers in a set of data?
There is no limit to the number of outliers there can be in a set of data.
Does outliers affects data?
No. Outliers are part of the data and do not affect them. They will, however, affect statistics based on the data and inferences based on the data.

How would you explain the outliers in chemistry?
In chemistry, outliers are data points that deviate significantly from the rest of the data set. Outliers can result from measurement errors, experimental uncertainties, or unexpected reactions. It is important to identify and address outliers in data analysis to ensure accurate and reliable results.
Is the median particularly sensitive to outliers in the data?
It is not.
What is the term that is used to describe data that does not fit with the rest of the data?
Outliers
What do outliers indicate?
In statistics, outliers are values outside the norm relative to the rest of collected data. Many times they can skew the results and distort the interpretation of data. They may or may not indicate anything significant; they might just be an anomalous data point that is not significant. It is difficult to tell.
Do they have outliers in a data set?
If the data numbers are all really close together than no. But if the data has numbers; for example: 12,43,45,51,57,62,90 (12 and 90 are the outliers) which are really far aprt, than yes.
