Answer: Find explanations below.
Step-by-step explanation:
1. A career as a Data Scientist would require data analysis skills.
2. The Data Scientist computes and analyzes large amounts of data from different sources and then makes useful interpretations with it. He needs skills In Statistics, Calculus, Probability, Programming, Excel, Visualization, Database management, and Machine Learning. He also needs a high level of accuracy when solving problems.
3. The median value is used when the data set contains values that repeat regularly and which contains some extremely high values. The mean value would aggravate towards higher values while the Median value would give a salary value that is an average of the data set. That is why the median value is used in salaries and housing prices calculations.
4. The dot plot is a simple scale representation of data values using dots to highlight the frequency of occurrences. I would use a dot plot to analyze quantitative data (like percentages, and decimals), and univariate data ( like mean, median, and mode).
The box plot analyzes a group of data in graphic styles. I would use it to determine the interquartile range, maximum, minimum, and median values. I would also use it to identify outliers.
5. Dot plot Strengths:
a. It is easy to plot the dots.
b. It is easy to interpret the data.
c. It shows the connection between the two data sets.
Dot Plot Weaknesses:
a. It shows the similarities between only two sequences.
b. The changes that occur between the data set cannot be easily detected.
c. It is time-consuming.
Box Plot Strengths:
a. Outliers are detected.
b. Indicates the 5-point summary.
c. It can compare more than two data set.
Box Plot Weaknesses:
a. Real values are lost.
b. The graph Is not easy to the sight.
6. The Income of the population of adult women would have a negatively skewed distribution.
