What else can I help you with?
When to use quartile deviation?
When you are looking for a simple measure of the spread of the data, but one which is protected from the effects of extreme values (outliers).
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.
Which of the following best describes the data distribution of the histogram below?
I'm unable to see the histogram you're referring to. However, to describe a data distribution, you can look for characteristics such as its shape (normal, skewed, bimodal), center (mean or median), spread (range or standard deviation), and any outliers. If you provide details about the histogram, I can help you analyze it!
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.
What data that does not fit well with the rest of a data set.?
They are called extreme values or outliers.
What you deciede to do when drawing conclusions about data?
Mostly through statistics, or summaries of the data set (depending on the type of data). There are many different statistical methods used to analyze the many different types of data that come from research studies or experiments. However if you just want a relatively quick and simplistic overview of a set of data than you should follow SOCS: Shape, Outliers, Center, Spread. Shape (the shape of the graphed data points) Outliers (any data points that fall outside the realm of "normal") Center (where the data points are mostly centered around) and Spread (the range of the data points). This should give you some immediate conclusions from your data.
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.
Who is statement below is correct concerning outliers?
To accurately assess the correctness of statements concerning outliers, I would need to see the specific statements in question. In general, outliers are data points that differ significantly from the overall pattern of data, and they can influence statistical analyses, such as mean and standard deviation. Identifying outliers is important for understanding data distribution and ensuring the robustness of statistical conclusions.

What are the most appropriate measures of center and spread for this data set?
The most appropriate measures of center for a data set depend on its distribution. If the data is normally distributed, the mean is a suitable measure of center; however, if the data is skewed or contains outliers, the median is more appropriate. For measures of spread, the standard deviation is ideal for normally distributed data, while the interquartile range (IQR) is better for skewed data or when outliers are present, as it focuses on the middle 50% of the data.
What is outliers for line pot?
Outliers in a line plot are data points that significantly deviate from the overall trend or pattern of the other data points. They can appear as points that are much higher or lower than the surrounding values, indicating unusual or exceptional cases. Identifying outliers is important as they can influence statistical analyses and interpretations. In a line plot, outliers may suggest anomalies, errors in data collection, or unique events warranting further investigation.
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 does Quartile 3 represent?
Quartile 3 (Q3) represents the value below which 75% of the data points in a dataset fall. It is a measure of the upper range of the data, indicating that 25% of the values exceed this point. Q3 is used in statistical analysis to understand the distribution and spread of data, particularly in identifying outliers and the overall shape of the data distribution.
What are the anomalous data points on the graph called?
Anomalous data points on a graph are commonly referred to as "outliers." These are values that deviate significantly from the overall trend or pattern of the dataset, often indicating variability in the measurement or potential errors. Identifying outliers is crucial for data analysis, as they can influence statistical results and interpretations.
Why are outliers bad?
Outliers can be problematic because they can skew statistical analyses, leading to misleading interpretations and poor decision-making. They may indicate data entry errors, measurement issues, or represent rare events that don't reflect the overall trend. In predictive modeling, outliers can disproportionately influence results, undermining the model's accuracy and reliability. Therefore, identifying and addressing outliers is crucial for maintaining the integrity of data analysis.
Is the median particularly sensitive to outliers in the data?
It is not.
