How to calculate quartile of journal?

To find a journal's quartile (Q1-Q4), you use citation databases like Web of Science (JCR) or Scopus (SCImago Journal & Country Rank), which rank journals in subject categories by metrics like Impact Factor (WoS) or CiteScore (Scopus); Q1 is the top 25%, Q2 the next, Q3 the next, and Q4 the bottom 25% in that specific field. You search the journal title on these platforms, and the site shows its specific quartile in its various subject areas, with Q1 being the best.

What is the formula for quartile?

Manual Method for Calculating Quartiles

You can calculate each quartile using the following formula: First Quartile (Q1) = (n + 1) x 1/4. Second Quartile (Q2), or the median = (n + 1) x 2/4. Third Quartile (Q3) = (n + 1) x 3/4.

What is the Q factor of a journal?

To determine the quartile (Q) of a journal, its impact factor or CiteScore is used, which reflects how many times articles from that journal have been cited in other scientific publications over a certain period of time. The classification of journals by quartile (Q) is based on the impact factor.

What is Q1, Q2, Q3, and Q4 journal ranking?

Q1 is occupied by the top 25% of journals in the list; Q2 is occupied by journals in the 25 to 50% group; Q3 is occupied by journals in the 50 to 75% group and Q4 is occupied by journals in the 75 to 100% group. The most prestigious journals within a subject area are those occupying the first quartile, Q1.

Is 4.8 a good impact factor?

Yes, a 4.8 impact factor is generally considered very good to excellent, especially as it's well above the typical average (often under 1) and falls into the "good" (around 3) to "very good/excellent" (5+) range for many fields, though its true value depends heavily on the specific academic discipline. It signifies strong visibility and citation rates, but you should always compare it to other journals in the same subject category (quartile/percentile) for the best evaluation. 

How to identify Q1, Q2, and Q3?

To identify Q1, Q2, and Q3, first order your data; Q2 (median) splits it in half; Q1 is the median of the lower half, and Q3 is the median of the upper half, effectively dividing the dataset into four equal parts, representing the 25th, 50th, and 75th percentiles, respectively. 

Why calculate quartiles?

Quartiles are values that divide a sample of data into four equal parts. With them you can quickly evaluate a data set's spread and central tendency, which are important first steps in understanding your data.

What is the Excel formula for quartile?

If your data is in column A, then click any blank cell and type “=QUARTILE(A:A,1)” for the first quartile, “=QUARTILE(A:A,2)” for the second quartile, and “=QUARTILE(A:A,3)” for the third quartile.

What is the Q level of a journal?

These groups are designated as Q1, Q2, Q3, and Q4. Q1 journals represent the top 25% of publication with highest impact, featuring the most influential and widely cited research. Conversely, Q4 journals fall within the bottom 25%, typically indicating lower visibility and citation rates.

How to calculate quartiles on paper?

How to find quartiles

1. Calculate n * (1 / 4).
2. If n * (1 / 4) is an integer, then the first quartile is the mean of the numbers at positions n * (1 / 4) and n * (1 / 4) + 1.
3. If n * (1 / 4) is not an integer, then round it up. The number at this position is the first quartile.

Is 2.5 a good impact factor for a journal?

Yes, an impact factor (IF) of 2.5 is generally considered good quality for a journal, placing it above average (most journals have IFs below 2), but not in the elite, top-tier range (which often starts at 5+ or 10+). It signifies decent visibility and citation frequency, but its "goodness" highly depends on the specific academic field, as citation patterns vary significantly between disciplines. 

How to check if a journal is Q1 or Q2?

To check if a journal is Q1 or Q2, use databases like Scopus or Web of Science (WoS) via your library, or free tools like SCImago Journal & Country Rank (SJR), searching for the journal and checking its percentile or quartile ranking within its subject category; Q1 is the top 25%, Q2 is 50-75%, etc., which indicates its impact relative to other journals in the field. 

Is Q3 always 75%?

The third quartile (Q3) is the 75th percentile, where the lowest 75% data lies below this point.

Quartiles. The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

How to know Q1 and Q3?

To find Q1 (First Quartile) and Q3 (Third Quartile), first order your data, then find the median (Q2) to split the data into lower and upper halves; Q1 is the median of the lower half, and Q3 is the median of the upper half, excluding the median itself if the total count is odd.
